Bruce; Ericsson, Anna; Lancia, David, Jr. published a patent.Category: esters-buliding-blocks The title of the patent was Preparation of pyrrolo and pyrazolopyrimidines as ubiquitin-specific protease 7 inhibitors. And the patent contained the following:
The invention relates to inhibitors of ubiquitin-specific protease 7 (USP7) of formula I useful in the treatment of cancers, neurodegenerative diseases, immunol. disorders, inflammatory disorders, cardiovascular diseases, ischemic diseases, viral infections and diseases, and bacterial infections and diseases. I [wherein X1 = C, S, or S(O); X2 = CH, CD, C-halo, etc.; R1 = H, D, -OH, etc.; R2 = (C1-C8) alkyl, aryl, heteroaryl, etc.; each R3 independently = D, aryl, heteroaryl, etc.; R4 = (C1-C6) alkyl, CD3, heteroaryl etc.; R5 and R5′ independently = H, D, (C1-C6) alkyl, (C2-C6) alkenyl, etc.; R6 = H, D, (C1-C6) alkyl, etc.; m = 0, 1, or 2; n = 0, 1, 2, or 3] or a pharmaceutically acceptable salt, hydrate, solvate, prodrug, stereoisomer, or tautomer, thereof, are claimed and exemplified. II was prepared via a multistep process (preparation given). I were evaluated for USP7 inhibitor activity using a Ubitquin-Rhodamine 110 assay (data provided). The experimental process involved the reaction of Methyl 1-methyl-4-oxocyclohexanecarboxylate(cas: 37480-41-4).Category: esters-buliding-blocks
