Exploring the structural activity relationship of the Osimertinib: A covalent inhibitor of double mutant EGFR tyrosine kinase for the treatment of Non-Small Cell Lung Cancer (NSCLC).

The USFDA granted regular approval to Osimertinib (AZD9291) on March 2017, for treating individuals with metastatic Non-Small Cell Lung Cancer having EGFR T790M mutation. Clinically, Osimertinib stands at the forefront for the treatment of patients with Non-Small Cell Lung Cancer. Osimertinib forms a covalent bond with the Cys797 residue and predominantly spares binding to WT-EGFR, thereby reducing toxicity and enabling the administration of doses that effectively inhibit T790M.

Design, synthesis and evaluation of rhodanine derivatives as aldose reductase inhibitors.

Aldose reductase (ALR) enzyme plays a significant role in conversion of excess amount of glucose into sorbitol in diabetic condition, inhibitors of which decrease the secondary complication of diabetes mellitus. To understand the structural interaction of inhibitors with ALR enzyme and develop more effective ALR inhibitors, a series of substituted 5-phenylbenzoate containing N-substituted rhodanine derivatives were synthesized and evaluated for their in vitro ALR inhibitory activity. Docking studies of these compounds were carried out, which revealed that the 5-phenylbenzoate moiety deeply influenced the key π-π stacking while 4-oxo-2-thioxothiazolidines contributed in hydrogen bond interactions.

Scattering signatures of suspended particles: an integrated system for combining digital holography and laser diffraction.

The use of laser diffraction is now common practice for the determination of an in situ particle size distribution in the marine environment. However, various imaging techniques have shown that particles vary greatly in shape, leading to uncertainty in the response of laser diffraction instruments when subjected to this diverse range of complex particles. Here we present a novel integrated system which combines both digital in-line holography and a LISST-100 type C, to simultaneously record in-focus images of artificial and natural particles with their small-angle forward scattering signature.

Insights through AM1 calculations into the structural requirement of 3,4,6-substituted-2-quinolone analogs towards FMS kinase inhibitory activity.

In the present work, we focused on quantification of activity of 3,4,6-substituted-2-quinolone derivatives with reference to structural properties. The multi-variant regression expressions were developed through sequential multiple linear regression technique, considering adjustable correlation coefficient (r(adj)(2)). The amalgamated best fit consensus scoring function showed coefficient of determination (0.
