Benzothiazole and Chromone Derivatives as Potential ATR Kinase Inhibitors and Anticancer Agents.

Despite extensive studies and the great variety of existing anticancer agents, cancer treatment remains an aggravating and challenging problem. Therefore, the development of novel anticancer drugs with a better therapeutic profile and fewer side effects to combat this persistent disease is still necessary. In this study, we report a novel series of benzothiazole and chromone derivatives that were synthesized and evaluated for their anticancer activity as an inhibitor of ATR kinase, a master regulator of the DDR pathway.

Small molecule NSAID derivatives for impairing powerhouse in cancer cells.

Mitochondrion emerged as an important therapeutic target for anti-cancer strategy due to its involvement in cancer progression and development. However, progress of novel small molecules for selective targeting of mitochondria in cancer cells remained a major challenge. To address this, herein, through a concise synthetic strategy, we have synthesized a small molecule library of indomethacin and ibuprofen (non-steroidal anti-inflammatory drugs, NSAIDs) derivatives having triarylphosphonium moiety for mitochondria localization.

Design, synthesis and biological evaluation of new Myo-inositol derivatives as potential RAS inhibitors.

Ras is a small family of GTPases that control numerous cellular functions like cell proliferation, growth, survival, gene expression, and is closely engaged in cancer pathogenesis. The ras-targeted methodology entails a holy grail in oncology. Nevertheless, there are no specific molecules reported targeting the same, although it is a known oncogene for more than three decades.

MDC1 depletion promotes cisplatin induced cell death in cervical cancer cells.

Objective: Cisplatin, the most common chemotherapeutic drug for the treatment of advanced stage cervical cancers has limitations in terms of drugs resistance observed in patients partly due to functional DNA damage repair (DDR) processes in the cell. Mediator of DNA damage checkpoint 1 (MDC1) is an important protein in the Ataxia telangiectasia mutated (ATM) mediated double stranded DNA break (DSB) repair pathway. In this regard, we investigated the effect of MDC1 change in expression on the cisplatin sensitivity in cervical cancer cells.
