AlCl3-mediated heteroarylation-cyclization strategy: One-pot synthesis of fused quinoxalines containing the central core of Lamellarin D

An inexpensive, practical and one-pot method has been developed for the synthesis of quinoxalines fused with pyrano[3,4-b]indole, the central core of Lamellarin D. The methodology involved construction of the central pyranone ring via an AlCl3-mediated heteroarylation-cyclization method. A number of compounds were prepared using this methodology, some of which were converted to the corresponding indol-3-ylquinoxaline derivatives. Several of the pyrano[3,4-b]indole fused quinoxalines showed promising growth inhibition of cervical and lung cancer cells and good interactions with topoisomerase I in silico.

Transition-Metal-Free Cross-Coupling Reactions in Dynamic Thin Films To Access Pyrimidine and Quinoxaline Analogues

The vortex fluidic device (VFD) is effective in modulating the synthesis of pyrimidine and quinoxaline-based compounds at room temperature and in high yield. The formation of the C?N bond occurs in the absence of a transition-metal catalyst, which avoids the contamination of the products with trace amounts of a transition metal. The systematic investigation of the operating parameters for the microfluidic platform in the confined operation mode established an optimum tilt angle of 45 for a 10 mm diameter borosilicate glass tube rotating at 5000 rpm.

HDAC as onco target: Reviewing the synthetic approaches with SAR study of their inhibitors

Even though one is moving towards the success in the discovery of efficient anti-cancer molecules, the drugs used in the treatment of various malignancies are found to possess toxicity and adverse reactivity in the human body that limit their use. The scientists all over the world are engaged in bringing up strategies that aim to develop small molecules that target the abnormal epigenetic factors. The discovery of the role of Histone deacetylases (HDACs) has promised to be a turning point in the treatment of various malignancies. Thus, the invention of potent and safe anticancer therapeutics agents with minimal adverse and side effects are still a major topic of concern and a huge number of research works have been reported in the past few years. This review has been written to discuss on the influence of Histone Deacetylases in cancer malignancies. We have tried to embrace majority of the developments made till date in the field of HDAC and its inhibitors herein. The drugs that are clinically applied, synthesis and SAR study that highlight the chemical groups responsible for evoking the HDAC inhibition and potential of various new classes of HDAC inhibitors (synthetic, hybrid and natural) have also been included.
