In recent years, the thienopyrazole moiety has emerged as a pharmacologically active scaffold with antitumoral and kinase inhibitory activity. In this study, high-throughput screening of 2000 small molecules obtained from the ChemBridge DIVERset library revealed a unique thieno[2,3-c]pyrazole derivative (Tpz-1) with potent and selective cytotoxic e...

In this study, we identified a novel pyrazole-based derivative (P3C) that displayed potent cytotoxicity against 27 human cancer cell lines derived from different tissue origins with 50% cytotoxic concentrations (CC50) in the low micromolar and nanomolar range, particularly in two triple-negative breast cancer (TNBC) cell lines (from 0.25 to 0.49 µM...

Recent evidences highlight the usefulness of small molecule (Histone deacetylase 4) HDAC4 inhibitors in the several preclinical paradigms. Major toxicity and mutagenicity issues associated with hydroxamate HDAC inhibitors, stimulated us to develop potent non‐hydroxamate inhibitors. In the present work a novel series of thiazolidinedione (TZD) deriv...

By high-throughput chemical library screening for novel therapeutic candidates, athienopyrazole derivative was categorized with cancer-selective cytotoxic effects. This compound exhibited effective and consistent cytotoxicity against arrange of human cancer cell lines at nanomolar to low micromolar concentrations through treatments exposing times o...

Prostate cancer is a common malignancy in men worldwide. In the initial treatment, ADT has been used as the cornerstone, but unfortunately, mainstream patients transition to the refractory state of prostate cancer, i.e., CRPC. Thus, newer therapeutics are required for the treatment of patients un or less responsive to ADT. Epigenetic aberrations, n...

Cancer is a heterogeneous disease, and its treatment requires the identification of new ways to thwart tumor cells. Amongst such emerging targets are glucose transporters (GLUTs, SLC2 family), which are overexpressed by almost all types of cancer cells; their inhibition provides a strategy to disrupt tumor metabolism selectively, leading to antitum...

Cancer cells increase their glucose uptake and glycolytic activity to meet the high energy requirements of proliferation. Glucose transporters (GLUTs), which facilitate the transport of glucose and related hexoses across the cell membrane, play a vital role in tumor cell survival and are overexpressed in various cancers. GLUT1, the most overexpress...

Epigenetics plays a fundamental role in cancer progression, and developing agents that regulate epigenetics is crucial for cancer management. Among Class I and Class II HDACs, HDAC8 is one of the essential epigenetic players in cancer progression. Therefore, we designed, synthesized, purified, and structurally characterized novel compounds containi...

1,4‐Triazolyl combretacoumarins have been prepared by linking the trimethoxyarene unit of combretastatin A4 with coumarins, via a 1,2,3‐triazole. For this, 4‐azidocoumarins were accessed by a sequential two‐step, one‐pot reaction of 4‐hydroxycoumarins with (benzotriazol‐1‐yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (BOP), followed by r...
