5 million compounds disappeared from ZINC today

Dear ZINC Users

I keep telling you there is a lot of turnover in the chemical marketplace, that ZINC changes rapidly.

Well, last night we removed nearly 5M formerly purchasable compounds from ZINC. As usual, we are also adding about 10,000 molecules per day. We plan to keep doing that pretty well continuously going forward.

We have added nearly a dozen catalogs in the last week, and we are in the process of adding a second dozen before the end of May.

Around here you run fast just to stay where you are.

Good luck to everyone!

John
