Synthesis, Biological Evaluation and in Silico Studies of Novel Urea/Thiourea Derivatives of Lenalidomide.

Designing new compounds from existing chemotherapeutic drugs to enhance inhibitory effects on tumor cells while overcoming multidrug resistance is one of the important strategies for new drug discovery in medicinal chemistry. A new series of urea and thiourea derivatives based on Lenalidomide as potential anticancer agents have been designed and synthesized. In vitro anticancer activity assay against Caki cancer cells and HUVEC endothelial cells revealed that 1-(4-methylphenyl)-3-[2-(2,6-dioxopiperidin-3-yl)-1-oxoisoindolin-4-yl]urea (11) exhibited the highest anticancer activity and selectivity in the series with IC values of 9.

New targets and biomarkers for doxorubicin-induced cardiotoxicity in humans: implications drawn from toxicogenomic data and molecular modelling.

The doxorubicin-induced cardiotoxicity continues to be a life-threatening adverse effect in the clinic. Doxorubicin-induced acute cardiotoxicity is reversible, whereas chronic cardiotoxicity is irreversible, leading to dilated cardiomyopathy and heart failure. The aim of this study was to identify the molecular mechanisms associated with doxorubicin metabolites in doxorubicin-induced chronic cardiotoxicity.

2,3-Dichloronaphthoquinone derivatives: Synthesis, antimicrobial activity, molecular modelling and ADMET studies.

In the present study, an intermediate namely 2-(3-bromopropylamino)-3-chloronaphthalene-1,4-dione was initially synthesized via the nucleophilic addition-elimination reaction between 2,3-dichloro-1,4-naphthoquinone and 3-bromo-1-aminopropane. Then a coupling reaction between the intermediate and piperazine derivatives yielded a number of 1,4-naphthoquinone derivatives. Spectroscopic analysis successfully characterized the products that were obtained in good yields.

Novel spiroindoline derivatives targeting aldose reductase against diabetic complications: Bioactivity, cytotoxicity, and molecular modeling studies.

Despite significant developments in therapeutic strategies, Diabetes Mellitus remains an increasing concern, leading to various complications, e.g., cataracts, neuropathy, retinopathy, nephropathy, and several cardiovascular diseases.

Structural Characterization of TRAF6 N-Terminal for Therapeutic Uses and Computational Studies on New Derivatives.

Tumor necrosis factor receptor-associated factors (TRAFs) are a protein family with a wide variety of roles and binding partners. Among them, TRAF6, a ubiquitin ligase, possesses unique receptor binding specificity and shows diverse functions in immune system regulation, cellular signaling, central nervous system, and tumor formation. TRAF6 consists of an N-terminal Really Interesting New Gene (RING) domain, multiple zinc fingers, and a C-terminal TRAF domain.
