old stale vendors removed

Dear ZINC Fans

As you know, we spend a lot of time trying to make sure you can buy the compounds in ZINC*. As the number of catalogs climbs towards 300, a number of catalogs were obviously stale. We wrote to the support email on the website, often multiple times. Finally, when we did not get an answer, we just removed the entire catalog from ZINC. Unfortunately, this included Tocris. Yeah, I know, can you believe it? But I couldn't get them to send me a database update, and the last info I had dated from 2005!

The website came back on last night, but we were too distracted to tell you. Now you know. maintenance going on

Dear ZINC (and other) users:

We are doing some maintenance over what we thought was a quiet weekend. ZINC is currently down (rebuilding indexes, don't ask!).

Thank you for your patience.

We can see that some people were using ZINC, and we've gone and interrupted your work! Sorry for the lack of warning!

EDASA 22000 compounds

to Whom it may concern,

I would like to upload in the Zinc Database the EDASA Compounds - in total are more than 22000 molecule.

Could you be as kind as to advise how I should proceed and who I should contact?

best regards


DOCK Blaster problems

Dear endlessly patient DOCK Blaster users:

We've discovered two different problems over the long weekend that were leading to job failures. To be brief, one was due to a license expiry that we thought was valid for another year, and the other was due to the queue being filled up, and as a consequence, jobs were failing due to over-commitment / incorrect allocation of resources.

We are working on it. Stand by.


the DOCK Blaster queue was stuck

Dear DOCK Blaster users

Due to very high demand, the DOCK Blaster queue had 750 "tasks" in the queue today, and in particular, 75 preliminary docking requests that had not been run, some from as long ago as two weeks.

I regret our failure to anticipate demand and to process these requests in a timely manner.

I have started to clear the backlog, which I hope will reduce if not clear out completely in the next day or two. I will also make changes so that this does not happen again.

-- John
