UORSY Covalent Fragments

Numerous approved drugs and drug candidates possess covalent mechanism of action and the interest for finding novel entities acted as covalent inhibitors has significantly increased.¹ As a result, the need for powerful tools for characterizing and optimizing covalent modifiers has aroused.

For creating our library of covalent fragments, we performed filtering based on fragment-like physicochemical profiles including molecules with certain functional groups or warheads.

Chemical classes included: acrylates and their active analogues; epoxides, lactones, lactams; sulfonyl fluorides; 2-chloropyridines; α,β-unsaturated sulfones and sulfonamides; activated cyano groups; aliphatic thiols; acetals and ketals.

Physicochemical profiles of UORSY covalent fragments library:

130<MW<320; 1<HbA<5; 0<HbD<3; -1.8<logP<4; 0<RotBonds<4; TPSA<95.

UORSY covalent fragments library is available in stock and could be delivered within 2 weeks in any customer-preferred format: as powders, dry films or DMSO solutions formatted in vials, 96 or 384-well plates. All compounds have a minimum purity of 90% assessed by ¹H NMR; analytical data is provided.
