27.07.2011 TOSLab in cooperation with System Biologie AG (Switzerland) offers a series of chromane and chromene derivatives relating to S-Equol. Prices and delivery times are available by request. Custom synthesis of similar substances (for example, with different substituents upon hydroxy groups) is possible. All compounds could be prepared in up to 1 kg amounts.
27.06.2011 TOSLab compounds for screening are updated; current total TOSLab Collection of Compounds consists of 17748 structures.
Updated TOSLab Building-Blocks are available now here. Total database is 1222 structures which are divided into three parts referring to their availability:
On-line Structure Search is available as usually.

06.04.2010 TOSLab Building-Blocks are updated and embraces 1140 structures at present. We are offering to your attention new imidazole derivatives, several examples of which are below:
Full list of TOSLab imidazole derivatives is available here. A part of these compounds are unique from TOSLab.
05.05.2009 TOSLab is pleased to present to your attention renewed web site-based search engine. On-line search could be performed by structure (exact or substructure) combined with the other search criteria. Now on, TOSLab Collection of Compounds (currently 16603 structures) and TOSLab Building-Blocks (currently 1121 structures) will be updated regularly (at least once in a month). We would be grateful for any comments and bug reports, which could improve the service. These could be sent to special E-mail.
Updated TOSLab Building-Blocks are available as well. As usually, total database (1121 structures) is divided into three parts divided into three parts referring to their availability:
Status A (239 compounds) - In stock;
Status B (210 compounds) - Could be prepared in 1-10 working days;
Status C (672 compounds) - Information on availability and delivery time by request;
101 Structures are novel TOSLab Building-Blocks.
TOSLab Combinatorial Library consists of 3467 structures. The database now is supplemented with chemical names and some Lipinski Rule descriptors.
29.12.2008 TOSLab Collection of Compounds contains various imidazole derivatives that could be used for a research and manufacturing in printed circuit board areas, electronics, as metal (including copper and copper alloys) surface treatment agents, water-soluble preflux, electrolyte additive for lead-acid batteries. An example of compounds potentially possessing such activities is available here (55 compounds).
09.04.2008 TOSLab announces Super Discount! We offer anabasein (3-(3,4,5,6-tetrahydropyridin-2-yl)pyridine dihydrochloride, TOS-BB-1321)
in up to 50 g amounts at the following prices: 5000 €/50 g, 1650 €/10 g, 1000 €/5 g 330 €/1 g. Greater amounts are available as well. The compound could be delivered in 1.0 - 2.5 months upon the order date. Anabasein is an analogue of natural alkaloid anabasine and could be used in different syntheses, e.g. involving CH-active 3-position.
