New research relevant to clopidogrel (PLAVIX)

[edit]

You're a recent contributor/editor for the topic clopidogrel (e.g., PLAVIX ) and I thought you might find the following relevant to that section:

http://www.sciencedaily.com/releases/2009/01/090128113250.htm

"ScienceDaily (Jan. 30, 2009) — Patients taking the common cardiac drug clopidogrel following a heart attack are at a significantly higher risk of a recurrence if they are also taking widely used acid-lowering medications called proton pump inhibitors, a new study has found.

The study, conducted over 6 years in thousands of heart attack patients aged 66 years and older, found a significantly increased risk of readmission for heart attacks if patients were taking one of several proton pump inhibitors, including omeprazole, lansoprazole, or rabeprazole. The investigators found no such association with the proton pump inhibitor pantoprazole or with other acid-lowering medications called H2 receptor antagonists."

I'm totally a wiki user, and not at all conversant with the rules / etiquette of editing/modifying so I'm staying clear....

Susan

Hi Susan. I apologize for taking so long to answer, but I'd somehow missed this message until now. I've actually contributed very little to the clopidogrel article over on Wikipedia, but I'll see about adding this information. Please feel free to add information yourself in the future: the "rules" are actually very simple, and there's plenty of help available!

Alogliptin

[edit]

Someone has left a comment on the Wikipedia alogliptin page saying that there is a double bond missing from the structure.

Fixed, thank you :) Fvasconcellos (t·c) 01:12, 10 March 2009 (UTC)[reply]
Thank you---that was fast!

Hi Fvasconcellos, i`ve seen your Mesna-Structure here on wiki and i`ve seen you´ve made it with chemsketch. is it possible that you send me the chemsketch file? i need it for a friend of mine.. would be super great!!! thanks in advance and here my e-mail-adress: <e-mail redacted> greetz anne

Erm... sure, will do. Best wishes, Fvasconcellos (t·c) 00:15, 11 March 2009 (UTC)[reply]

Haikouichthys Image

[edit]

Hi. I have recently uploaded a new version of an illustration of the chordate Haikouichthys at the English Wikipedia, considering how I cannot replace the existing file Haikouichthys4.png. Even here at Wikimedia Commons I cannot upload the new version of the file in place of the existing one. So may I ask that someone either replace the image with this: http://en.wikipedia.org/wiki/File:Haikouichthys5.png here and delete the newer one I uploaded, or upload the new version onto Wikimedia Commons and delete the old one? Thank you, Giant Blue Anteater (talk) 23:53, 21 April 2009 (UTC)[reply]

Hi there. I've uploaded the new version over the old one—I wonder why you were unable to do this; did you get some kind of error message? I'll delete the local (Wikipedia) version of Haikouichthys5.png. Best, Fvasconcellos (t·c) 12:19, 22 April 2009 (UTC)[reply]
Thanks! Your service is appreciated! And no, I didn't get an error message. But that dosen't matter much now. Giant Blue Anteater (talk) 21:49, 22 April 2009 (UTC)[reply]
Anytime. Best, Fvasconcellos (t·c) 15:09, 24 April 2009 (UTC)[reply]


The factual accuracy of the chemical structure Image:Acetophenazine.svg is disputed

[edit]
Dispute notification The chemical structure Image:Acetophenazine.svg you uploaded has been tagged as disputed and is now listed in Category:Disputed chemical diagrams. Images in this category are deleted after one month if there is no upload of a corrected version and if there is no objection from the uploader or other users.

Hello, Fvasconcellos!
Tip: Add categories to your files
Tip: Add categories to your files

Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.

Here's how:

1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:

2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.

[[Category:Category name]]

For example, if you are uploading a diagram showing the orbits of comets, you add the following code:

[[Category:Astronomical diagrams]]
[[Category:Comets]]

This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".

When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations").

Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.

Increase res

[edit]

Hey Fvasconcellos. One question: When I am preparing some protein structures (e. g. this) using Pymol, exporting results only in a moderate res. How to increase the resolution? Cheers, --Yikrazuul (talk) 17:11, 14 July 2009 (UTC)[reply]

Ok, I've found the command. BUT - I have problems to get rid of the background. If it's black, someone could critize that. If I don't save transparency (using IrfanView), than I get this. If you zoom in, than you see my problem...What is your advise? Cheers, --Yikrazuul (talk) 17:22, 14 July 2009 (UTC)[reply]
I see you found the command to increase the resolution :) Render the image at a very high resolution (like 2000px on the smaller side; this image could be rendered with png 1938,2384 ) and then resize it to 1000px or so in IrfanView or GIMP to fix the aliased edges. Do you know PyMolWiki? There's a lot of information there. Fvasconcellos (t·c) 21:19, 14 July 2009 (UTC)[reply]
Nice work, by the way! Fvasconcellos (t·c) 21:19, 14 July 2009 (UTC)[reply]

Hi there - your previous Phosphoenolpyruvate image was correct, vice the current one

[edit]

I'm not sure how to replace it or I would. In any case, thought you should know. I'm not sure why you changed it, but the previous one is correct. Thanks for all your contributions.

Hi there! What do you mean? There are only 6 oxygen atoms in phosphoenolpyruvate. Best, Fvasconcellos (t·c) 02:56, 19 August 2009 (UTC)[reply]


Complex II Diagram

[edit]

I believe that your diagram of succinate dehydrogenase (SDH, complex II of the mitochondrial electron transport chain) is inaccurate. The mammalian enzyme does not contain a heme and does not pass its electrons through a heme. There may be some confusion about this because some bacteria have heme b cytochromes that bind SDH to the cell membrane. However, bacteria and mammalian mitochondria are different. RayMosteller, Assoc Prof of Biochemistry & Molecular Biology, USC.

http://commons.wikimedia.org/wiki/File:Complex_II.svg

Hello, Professor, isn't heme present in most SQR complexes? I had no idea that mammalian complex II does not contain a heme group. I'll gladly alter the image if necessary, but as I'm not its author (I only converted it to a vector file format), you should probably contact him: Tim Vickers at the English Wikipedia. Best wishes, Fvasconcellos (t·c) 02:23, 2 September 2009 (UTC)[reply]

Clofarabine structure

[edit]

Thanks very much for your contributions. I wanted to note that your structure of clofarabine is not quite correct - the 2´-fluoro group should be on the beta face of the ribose ring, consistent with the stereochemistry in arabinose. Thanks!

Thank you for bringing this to my attention. I'll correct it as soon as possible. Fvasconcellos (t·c) 15:49, 30 September 2009 (UTC)[reply]
Fixed! Fvasconcellos (t·c) 19:36, 18 October 2009 (UTC)[reply]

Error in sarkosyl image

[edit]

Hi,

Your rendering of sodium lauroyl sarcosinate is missing an additional carbon on the tail. Lauryl or lauroyl indicates 12 carbons after the carbonyl group. Also, the molecular formula indicates that there are 15 carbons, not 14 as in your image.

I'm sorry, but the image is perfectly accurate; compare it to [1]. There are indeed 15 carbons in the image, not 14 (you can count them again if you like). Best wishes, Fvasconcellos (t·c) 19:36, 18 October 2009 (UTC)[reply]

Hello, the fifth stereo center in this formula is missing. PubChem picture is incorrect, see the IUPAC name (1S,2S,3S,4R)-3-[(1S)-1-acetamido-2-ethyl-butyl]-4- (diaminomethylideneamino)-2-hydroxy-cyclopentane- 1-carboxylic acid. Could you please change it? Regards. --Ayacop (talk) 19:10, 29 October 2009 (UTC)[reply]

Fixed. Thank you for bringing this to my attention! Fvasconcellos (t·c) 20:55, 30 October 2009 (UTC)[reply]

Molybdopterin

[edit]

See User talk:Edgar181#Molybdopterin now User talk:Edgar181/Archive2009#Molybdopterin --Leyo 10:42, 22 December 2009 (UTC)[reply]

I would like to finally decide whether your two disputed images of molybdopterin should be kept or deleted. Do you agree that they show an incorrect structure? --Leyo 22:42, 21 September 2010 (UTC)[reply]

Lactacystin structure

[edit]

Hi. In the structure of Lactacystin (http://en.wikipedia.org/wiki/File:Lactacystin.svg) one does not need to explicitly draw the wedge and the hydrogen in the 2-methylpropyl moiety. No stereocenter there. Cheers, Kalju

Thank you for letting me know. I instinctively went back to the source to check—and can't find lactacystin in the article! Best wishes, Fvasconcellos (t·c) 23:39, 5 March 2010 (UTC)[reply]

The chemical structure you have uploaded and re-uploaded for radezolid (CAS 869884-78-6) is incorrect. Please check your WHO reference carefully; the C-5 decoration is not an ester but rather an acetamide. You may also consult the following web page: http://www.bocsci.com/products.asp?op=search. Of course, you may also check out the "Publications and Posters" section of the relevant company's website (http://www.rib-x.com) for the structure. Thank you.

Yes, of course. Thank you for noticing. I only uploaded the structure once—what do you mean by reuploaded? Best, Fvasconcellos (t·c) 02:30, 19 March 2010 (UTC)[reply]

How to credit you for Substance P space-filling model

[edit]

Hello - I would like to use your space-filling Substance P model in a talk I'm giving. How should I credit you? The images I'm using typically receive a "© date & name" next to them.

Hi there! This reply is probably coming too late, but I have released that image into the public domain. No credit is necessary. I hope you were able to use it! Best, Fvasconcellos (t·c) 12:50, 6 May 2010 (UTC)[reply]

Hi Fvasconcellos. Your images has been tagged. Can you please address the dispute? --Leyo 17:10, 17 April 2010 (UTC)[reply]

Hi Leyo, I'll see what I can do. I haven't been around much. Fvasconcellos (t·c) 12:50, 6 May 2010 (UTC)[reply]
And... done :) Fvasconcellos (t·c) 17:55, 20 June 2010 (UTC)[reply]

Hi Fvasconcellos, is there a special reason why you drew the bonds to the two methyl groups as triangulars? This suggests a stereogenic center which is not present. I would suggest to keep the formula flat. --Mabschaaf (talk) 17:46, 1 May 2010 (UTC)[reply]

Hi there, that was just to imply the true geometry (as the groups are not coplanar), I used to do that in my old structures—before I learned it's usually inappropriate. I'll correct it as soon as I can. Best, Fvasconcellos (t·c) 12:50, 6 May 2010 (UTC)[reply]
Hi again... now fixed. I apologize for taking so long to address this. Best, Fvasconcellos (t·c) 17:37, 20 June 2010 (UTC)[reply]

ADP-ribose wrong configuration

[edit]

Hi. I found a mistake in your structure of ADP-ribose. It's actually a mistake found in several textbooks and research papers. The stereochemical configuration of each of the chiral centres in the left-hand ribose (the one remote from the adenine) is wrong. As shown, this ribose is L-ribose, whereas the one attached directly to the adenine is D-ribose. It would be helpful if you modified it. Thanks.

Hi there, I just came to the same conclusion as above. The ribose not attached to adenine is currently L-ribose, but should be D-ribose instead. In other words, it should be identical with the adenine-attached one, like for example here: File:NAD+ phys.svg. This affects files File:Adenosine diphosphate ribose.svg and File:Adenosine diphosphate ribose 3D.png Could you please make the corrections? Thanks for all your work. --Vlachj (talk) 23:10, 28 September 2015 (UTC)[reply]

Error in the structure of Cefaclor

[edit]

Hello, I just want to mention that your stucture of structure is not correct: a chiral carbon is missing. Please modify your picture according to this picture. Thank you Snipre (talk) 16:15, 28 May 2010 (UTC)[reply]

Fixed, thank you! Best, Fvasconcellos (t·c) 17:31, 20 June 2010 (UTC)[reply]

Hi, in this structural formula is missing the stereochemical information at C-6. Perhaps you could add it? Thanks a lot --Mabschaaf (talk) 18:16, 8 August 2010 (UTC)[reply]

IMHO, there are two chiral centers. --Leyo 15:18, 9 August 2010 (UTC)[reply]
Yes indeed :) Will upload a new version ASAP. Fvasconcellos (t·c) 01:34, 12 August 2010 (UTC)[reply]
Done. Thank you for bringing this to my attention—and thank you, Leyo, for reminding me of the chiral center at the glutamate moiety :) Fvasconcellos (t·c) 00:25, 13 August 2010 (UTC)[reply]

Hi Fvasconcellos, this one misses info on a stereo bond, where cyclopropyl binds. Good occasion to say thanks for your work, though. Cheers --Ayacop (talk) 15:42, 8 October 2010 (UTC)[reply]

H-bonding

[edit]

After all your fine work, I hate to be a bearer of bad news. If you want to portray the lowest energy conformation of any of your amino acids, such as gabapentin, you need to account for the hydrogen bonding between the hydrogen on the carboxylic acid and the lone pair on the amine. A quick calculation on the DFT optimized structures (B3LYP//6-31G*) showed that the H-bonded structure is 8 kcal/mol (33.5 kJ/mol) lower than the your free amine conformation. Laburke (talk) 19:06, 14 May 2011 (UTC)[reply]

Hi there. Not bad news at all—as one of my oldest models, that one was created without any sort of optimization; I am fully aware of its relative "inaccuracy" :) Please feel free to replace it with an optimized model you may have created. Thank you for bringing this to my attention, and best wishes! Fvasconcellos (t·c) 22:20, 20 May 2011 (UTC)[reply]

Hi Fvasconcellos, I recognized that in the structure above the height of the "L"s is a little bit bigger than the height of the "C"s. This may cause some trouble if the "L"s are misinterpreted as lone pairs. Could you please fix that? Thx --Mabschaaf (talk) 17:53, 19 June 2011 (UTC)[reply]
