Identification and Preclinical Evaluation of the Bicyclic Pyrimidine γ-Secretase Modulator BMS-932481
摘要:
A triazine hit identified from a screen of the BMS compound collection was optimized for potency, in vivo activity, and off-target profile to produce the bicyclic pyrimidine gamma-secretase modulator BMS-932481. The compound showed robust reductions of A beta(1-42) and A beta(1-40) in the plasma, brain, and cerebrospinal fluid of mice and rats. Consistent with the gamma-secretase modulator mechanism, increases in A beta(1-37) and A beta(1-38) were observed, with no change in the total amount of A beta(1-x) produced. No Notch-based toxicity was observed, and the overall preclinical profile of BMS-932481 supported its further evaluation in human clinical trials.

trials. Alternatively, small molecules targeting the chemokine instead of the receptor provide a largely unexplored space for therapeutic development. Here we report that trisubstituted 1,3,5-triazines are competent ligands for the sY12-binding pocket of CXCL12. The initial hit was optimized to be more synthetically tractable. Fifty unique triazines were synthesized, and the structure–activity relationship
Suitable one-pot reaction conditions are suggested to prepare, in good overall yields, some 2-(alk-1′-ynyl)- and 2-alkyl-4,6-dialkylamino-1,3,5-triazines via reaction of cyanuricchloride with Grignard reagents followed by amination.

To expand the diversity of 1,3,5-triazine libraries to aryl and alkyl functionalities through the C–C bond, we employed a novel orthogonal synthesis via Grignard monoalkylation or monoarylation of cyanuric chloride in solution to prepare aryl- or alkyl-substituted triazine building blocks. These aryl- or alkyl-substituted triazine building blocks were captured by a resin-bound amine, followed by amination
