SVG Format

Thank you so much for awarding me the chemistry bond star. I feel Wikipedia is an incredible resource for almost anyone, and continue to improve articles and identify vandals as best I can. I am curious as if you know how to create SVG files on the Macintosh platform. I've tried to use Inkscape, but haven't succeeded (the program does not launch, but simply quits upon so). The PNG files I've uploaded are high-resolution and, as I feel, as high-quality as Wiki articles would need. However, I am aware that SVG is the preferred format for chemical structures. Have you any suggestions regarding this matter? Secondly, is there a specific page on Wikipedia that identifies articles needing IUPAC naming and/or chemical structures of high-quality?

review

•  Comment I note that the image presented doesn't match the blazon in the description. For one, the blazon implies a violation of the Rule of tincture by placing a yellow sun on a white shield. The actual image, though, actually has a yellow sun on a blue shield bordered in white, which is allowable. The blazon also specifies that the stars form an equilateral triangle, which they do not in this image. Powers 12:30, 2 June 2008 (UTC)
  •  Comment Yes, I'm aware of that. None of the source images (Image:Gerb gag.jpg, tr:Resim:Gagavuzya armsı.png) match the blazon either; you can quite clearly see here and here that the sunburst is always placed on a blue field. Since the blazon was translated into English (by the FOTW folks—I don't speak Moldovan), I'm unsure as to where the "white field" came from; perhaps it would be best to remove the blazon from the description entirely. The placement of the stars was indeed off by a few pixels, and has been fixed. Fvasconcellos (t·c) 13:31, 2 June 2008 (UTC)
    •  Comment I do appreciate that the actual images in use also contradict the specified blazon; it's not so much a criticism of the image (which is fine) but of the description. Minor enough that I didn't feel comfortable opposing, of course, but it's something to be considered. Obviously the blazon text comes straight from Moldovan law, but if there is an explanation for the discrepancy, the description seems incomplete without it. If not, oh well; though an acknowledgment of the discrepancy would also be helpful for future viewers. (I also still wonder about the stars; moving the top one down seems to make the arrangement even less equilateral than it was before. Maybe it's my monitor's aspect ratio.) Powers 19:02, 2 June 2008 (UTC)
      •  Comment OK, I have found the actual Legal Code of Gagauzia and, although the translation is even less idiomatic (!), it does specify a blue field—apparently, the "white" was indeed a FOTW slip-up. I'll amend the image description accordingly. As for the stars, they do form an equilateral triangle in the existing images, but not as you probably expected (I did at least)—that is, with the center of each star being one vertex of the triangle—but like so. I'd gladly have arranges them with each star as one vertex of the triangle, but that would conflict with every existing image out there! Fvasconcellos (t·c) 21:29, 2 June 2008 (UTC)
        • OK, things are starting to make sense now. =) Thanks for your research. I do agree that the existing images clearly show the stars arranged as you have them. What's interesting is that the stars on Gagauzia's flag appear to be equilateral in the sense I was expecting, even though they're described the same way in the Legal Code. Ah well. Nice work at any rate. Powers 22:46, 2 June 2008 (UTC)
•  Support I guess I'm going to support. I don't feel like I have a good grasp of the scope criterion, but this almost certainly is the most valuable image within that scope and deserves at least some recognition. Powers (talk) 14:06, 12 June 2008 (UTC)
  •  Comment Regarding the scope it is surely a quite narrow and specialized scope, but I still think the scope as such is useful for WMF projects (it is used). It also seems to be high quality work, which a lot of effort has gone into. I know nothing about coats of arms so I will abstain from voting. -- Slaunger (talk) 22:37, 12 June 2008 (UTC)

Protein structures

Hi, I took a look at the gallery and I'm very impressed with the protein structures. How do you make those? Do you have a 3D file for each one - what format? I think the lack of 3D on Commons is a great loss. Dhatfield (talk) 13:21, 26 June 2008 (UTC)

Strange SVG error

Hi there, any idea how to fix the text in this? 03:09, 18 July 2008 (UTC)

Done. The author specified a typeface (Helvetica Neue) that isn't supported in MediaWiki, and since he didn't specify a font stack, the renderer defaults to Bitstream Vera Sans, which is is not at all metrically compatible with Helvetica. I just switched it to Arial and it's fine now. Fvasconcellos (t·c) 14:53, 18 July 2008 (UTC)

Image:Molybdopterin.svg

Oi! Estava a olhar para esta imagem e o meu namorado, que trabalhou um pouco com enzimas contendo molibdopterina, começou a barafustar com a estrutura, rs. Os enxofres ligados ao molibdénio não deveriam estar protonados (quando estão ligados ao metal) e o molibdénio, embora não perfeitamente no plano dos anéis, também não deveria estar atrás do plano, deveria antes formar um anel com os enxofres... Bem, não mates o mensageiro, ele é que se queixou, rsrsrs. De onde the inspiraste para esta estrutura? Não sei se existem diferentes versões. Abraço, Patrícia ^msg 22:00, 18 September 2008 (UTC)

Ah, confundi os tracejados. Bem, a ligação metal-enxofre pode ser descrita com um traço normal; mesmo sendo um "composto de coordenação", é uma ligação química com tanto direito como as outras, rs. Não acho necessário mudar o nome da imagem, não existe molibdopterina que não seja cofactor, de qualquer modo... Muito obrigada! Patrícia ^msg 19:44, 22 September 2008 (UTC)

Na verdade, como são, sei lá, cinco ou seis grupos no mundo inteiro que se preocupam sobre o assunto :D, a nomenclatura não está muito definida; o correcto parece chamar o cofactor de "piranopterina" (pyranopterin), pois pode ligar molibdénio ou tungsténio. Só que não há evidência de um metal poder ser trocado pelo outro in vivo (tanto quanto saiba, mas de facto não é a minha especialidade) e tanto quanto me lembro (deveria ter procurado um pouco mas agora deu-me a preguiça :P) há organismos que usam um metal ou o outro. Ou seja, a piranopterina torna-se molibdopterina quando liga um molibdénio e tungstopterina (?) quando liga um tungsténio... não sei se ajudei ou confundi, hehehe. Patrícia ^msg 22:07, 22 September 2008 (UTC)

Image:Butylscopolamine skeletal.svg

Hello,

the structure

of Butylscopolamine is wrong:

• the quaternary N has the wrong configuration (i. e. the methyl and butyl rests have to be switched, unlike Image:Ipratropium.svg or en:oxitropium)
• the epoxyde carbons have the wrong configuration (i. e. the oxygen has to face the other direction, like Image:L-Scopolamin.svg or en:oxitropium)

I would appreciate a correction of this formula, since it is used in 5 other wikipediae. --131.220.136.195 14:19, 22 September 2008 (UTC)

Here is a link to the correct formula: [1]

Will do. I'm not sure the positions of methyl/butyl should be reversed, though; see e.g. Studies in Natural Products Chemistry and Sigma-Aldrich. Best wishes, Fvasconcellos (t·c) 21:23, 22 September 2008 (UTC)

Well, I consulted a whole lot of schoolbook of medicinal chemistry and also my profs in my pharmaceutical study said that it is the main difference between butylscopolamine and ipratropium or oxitropium. --131.220.136.195 12:00, 23 September 2008 (UTC)

Add-on: please consult the en:European Pharmacopoeia 5 or the en:Merck Index, both of which see the butyl rest equatorial and the gmethyl rest axial. --131.220.136.195 15:19, 23 September 2008 (UTC)

see here...

All right, then. I'll upload a new version shortly. Thanks again for bringing this to my attention! Fvasconcellos (t·c) 16:18, 23 September 2008 (UTC)

BTW: There is an ongoing discussion on the German Wikipedia. --Leyo 18:10, 23 September 2008 (UTC)

Which I cannot take part in—I can't speak a word of German. Google's not much help (I don't think it can cope with the chemistry jargon :) Fvasconcellos (t·c) 20:43, 23 September 2008 (UTC)

OK, an English summary of that comment:

Chemical Abstracts Service says that the CAS number 7182-53-8 has no defined configuration at the nitrogen. The different configurations in books are caused by the fact that the configuration (methyl and butyl group) has to be drawn in some way. Both diastereomeric forms have CAS numbers: the diastereomer in your image 790180-31-3 (bromide: 150521-10-1), the other diastereomer with exchanged butyl and methyl group 768332-46-3 (bromide: 150521-07-6). I venture to doubt that there is only one diastereomeric form present in commercial products.

Did that help? --Leyo 21:03, 23 September 2008 (UTC)

Yes indeed :) Thanks. I've (finally) uploaded the image as requested, though I'm still not so sure it was necessary—hope that helps! Fvasconcellos (t·c) 21:06, 23 September 2008 (UTC)

I think both diastereomeric forms should be shown in the article. --Leyo 23:50, 23 September 2008 (UTC)

I don't, because only one is pharmaceutically relevant. I. e. the one which is listed in the pharmacopoeiae of this world. --131.220.136.195 07:36, 24 September 2008 (UTC)

Well, the other structure is just an impurity, not the drug itself. I don't know whether there is any relevance, except you want to mention the impurities in the article. --91.55.122.205 11:28, 28 September 2008 (UTC)

Very often, enantiomeric forms of the same drug may have different potencies, but more importantly, different physiological properties, cf. thalidomide. Compendia very often list stereochemical mixtures for drugs when they are first synthesized and tested. Then, if a new physiological property is discovered for a distinct stereoisomer, a new drug name is dreamed up by marketeers and this name enters the compendia. It is essential to Pharmacology that stereoisomers be listed in the originally named drug. This is not a blind exercise in reductive logic. Laburke (talk) 15:51, 14 May 2011 (UTC)

w:Bortezomib

Hi, I'm going through our SDF trying to validate some of our chemboxes and drugboxes, and I noticed that Image:Bortezomib.svg appears to be the enantiomer of the title compound, assuming the IUPAC name is correct. Can you check your sources, and find out if the IUPAC name is wrong and your structure is right, or vice versa, then make the necessary adjustments? Thanks, Walkerma (talk) 04:58, 13 October 2008 (UTC)

I just checked in the SDF file provided by CAS, and that also appears to indicate that you've drawn the enantiomer. Can you fix this, unless I made a mistake? Thanks, Walkerma (talk) 05:40, 13 October 2008 (UTC)

Yep, I've just checked as well. One more for the fix-it pile... Thanks for the note! Fvasconcellos (t·c) 12:01, 13 October 2008 (UTC)

Thanks a lot for fixing that. It would be great if you could check a few, take a look at w:Wikipedia:WikiProject Chemicals/Chembox validation and see if you can help. Many of them are drugboxes, so your expert eye would be useful. Also see the talk page for some outstanding issues.
