building blocks (key components in clickchemistry). We report herein a highly robust and efficient strategy for high-throughput synthesis of a 325-member azide library. The method is highlighted by its simplicity and product purity. The utility of the library is demonstrated with the subsequent “click” synthesis of the corresponding bidentate inhibitors against PTP1B.

homology-2 domain containing protein tyrosine phosphatase-2 (SHP2) plays a pivotal role in growth factor and cytokine signaling. Gain-of-function SHP2 mutations are associated with Noonan syndrome, various kinds of leukemias, and solid tumors. Thus, there is considerable interest in SHP2 as a potential target for anticancer and antileukemia therapy. We report a salicylicacidbased combinatorial library approach

We uncovered that mPTPB subverts the innate immune responses by blocking the ERK1/2 and p38 mediated IL-6 production and promoting host cell survival by activating the Akt pathway. We identified a potent and selectivemPTPBinhibitor I-A09 with highly efficacious cellular activity, from a combinatorial library of bidentate benzofuran salicylic acid derivatives assembled by click chemistry. We demonstrated

Searching for new active molecules against M. Bovis BCG and Mycobacterium tuberculosis (MTB) H37Ra, a focused of 1,2,3-triazoles-incorporated 2,4 thiazolidinedione conjugates have been efficiently prepared via a click chemistry approach cyclocondensation of 4-amino-N-(5-methylisoxazol-3-yl)benzenesulfonamide (4), aryl aldehyde (5a–l), and mercapto acetic acid (6) with good to promising yields.

agents has prompted the design and synthesis of a library of twenty-six aryloxy-tethered and amide-linked symmetrical 1,2,3-triazoles (8a–z) using a copper(I)-catalyzed click chemistry approach. All the synthesized compounds have been screened for their in vitro antifungal activity against four different fungal strains as well as the enzymatic study for the inhibition of 14 α-demethylase enzyme.
