On June 25, 2020, Brenneman, Jehrod Burnett; Krall, Elsa Beyer; Schlabach, Michael; Wylie, Andrew Alistair published a patent.Recommanded Product: 6-Chloro-4-methoxy-1H-pyrazolo[3,4-d]pyrimidine The title of the patent was Preparation of substituted pyrazolopyrimidines and substituted purines and their use as ubiquitin-specific-processing protease 1 (USP1) inhibitors. And the patent contained the following:
The present disclosure provides compounds having formula I and the pharmaceutically acceptable salts and solvates thereof, wherein X1, X2 is independently N and CR2; R1 and R2 are independently H, halo, cyano, (un)substituted alkyl, etc.; R3 is (un)substituted Ph, pyridinyl, pyrazolyl, etc.; X11 and X12 is independently N and CH; R5′ is H, (un)substituted C1-6alkyl, (un)substituted C1-6alkoxy, etc.; R5 is (un)substituted C1-6alkyl, (un)substituted C2-6alkenyl, C1-6haloalkyl, etc.; R6 and R7 is independently H, halo, CN, (un)substituted alkenyl, etc. The present disclosure is also directed to the use of compounds of Formula I to inhibit a USP1 protein and to treat a disorder responsive to the inhibition of USP1 proteins and USP1 activity. Example compound II was prepared via a multistep procedure (procedure given). From the assay, it was determined that example compound II exhibited IC50 value of > 200 nM towards USP1. The experimental process involved the reaction of 6-Chloro-4-methoxy-1H-pyrazolo[3,4-d]pyrimidine(cas: 98138-75-1).Recommanded Product: 6-Chloro-4-methoxy-1H-pyrazolo[3,4-d]pyrimidine
