The present invention provides triazolotriazine derivatives of formula (1) as A2A receptor antagonists. Compounds of formula (1) and pharmaceutical compositions including the compounds can be used for the treatment of disorders related to A2A receptor hyperfunctioning, such as certain types cancers. Compounds of formula (1) and methods of preparing the compounds are disclosed in the invention.
Protein tyrosine phosphatases (PTPases) such as PTP1B can play a role in regulating a wide variety of cellular responses such as insulin signaling. Substituted thiophene compounds such as, for example, 2-carboxyl, 3-carboxymethoxy, 5-aryl substituted thiophenes, can inhibit PTP1B and thereby induce greater insulin sensitivity. Accordingly, PTP1B inhibition can provide an alternate treatment for PTPase-mediated disorders such as diabetes.

A robust ‘catch, cyclize, and release’ preparation of 3-thioalkyl-1,2,4-triazoles mediated by the polymer-bound base P-BEMP is described. This reengineered synthesis combines the chemical efficiency of the classical synthesis (three steps; three diversity points) with the practical benefits of resin-bound reagents (use of excess reagents to drive reactions to completion, no purification of intermediates
imidazolidin-2-one was introduced as the linker for novelHDACinhibitors. A focused library of 20 compounds was designed and synthesized, among which eight compounds showed equivalent or higher potencies against HDAC1 as compared to vorinostat. In vitro antitumoractivity assays in HCT-116, PC-3 and HL-60 cancer cells revealed six compounds with potent antitumoractivities, and compound 1o showed 6- to 9-fold higher
