Benzodiazepines (BZDs) represent a diverse class of bicyclic heterocyclic molecules. In the last few years, benzodiazepines have emerged as potential therapeutic agents. As a result, several mild, efficient and high yielding protocols have been developed that offer access to various functionalized benzodiazepines (BZDs). They are known to possess a wide array of biological activities such as anxiolytic, anticancer, anticonvulsant, antipsychotics, muscle relaxant, anti-tuberculosis, and antimicrobial activities. The fascinating spectrum of biological activities exhibited by BZDs in various fields has prompted the medicinal chemist to design and discover novel benzodiazepine-based analogs as potential therapeutic candidates with the desired biological profile. In this review, an attempt has been made by to summarize (1) Recent advances in the synthetic chemistry of benzodiazepines which enable their synthesis with desired substitution pattern; (2) Medicinal chemistry of BZDs as therapeutic candidates with promising biological profile including insight of mechanistic studies; (3) The correlation of biological data with the structure i.e. structure-activity relationship studies were also included to provide an insight into the rational design of more active agents.

This study explored the biodegradation mechanisms of oxytetracycline (OTC/O) and electrochemical characteristics from the perspective of bacterial community shift and OTC resistance genes in dual graphene modified bioelectrode microbial fuel cell (O-D-GM-BE MFC). In phylum level, Proteobacteria was accounted to 95.04% in O-GM-BA, Proteobacteria and Bacteroidetes were accounted to 59.13% and 20.52% in O-GM-BC, which were beneficial for extracellular electron transport (EET) process and OTC biodegradation. In genus level, the most dominant bacteria in O-GM-BA were Salmonella and Trabulsiella, accounting up to 83.04%, moreover, representative exoelectrogens (Geobacter) were enriched, which contributed to OTC biodegradation and electrochemical performances; abundant degrading bacteria (Moheibacter, Comamonas, Pseudomonas, Dechloromonas, Nitrospira, Methylomicrobium, Pseudorhodoferax, Thiobacillus, Mycobacterium) were enriched in O-GM-BC, which contributed to the maximum removal efficiency of OTC; coding resistance genes of efflux pump, ribosome protective protein and modifying or passivating were all found in O-GM-BE, and this explained the OTC removal mechanisms from gene level.

Histone acetyltransferases (HATs) are epigenetic drivers that catalyze the acetyl transfer from acetyl-CoA to lysines of both histone and non-histone substrates and thereby induce transcription either by chromatin remodeling or direct transcription factor activation. Histone deacetylases (HDACs) conduct the reverse reaction to counter HAT activity. Physiological processes such as cell cycle progression or apoptosis require a thoroughly balanced equilibrium of the interplay between acetylation and deacetylation processes to maintain or, if required, alter the global acetylome status. Aberrant HAT activity has recently been demonstrated to play a crucial role in the progression of various diseases such as prostate, lung, and colon cancers as well as glioblastomas and neurodegenerative diseases. Recent investigations have aimed for the identification of HAT modulators to further decipher the complexity of acetyl transferase related signaling cascades and discover potential leads for drug design approaches. HDACs have been extensively characterized and targeted by small molecules, including four FDA-approved HDAC inhibitors; in contrast, HATs have not been active targets for therapeutic development. This review will summarize the status of HAT associated diseases and the arsenal of currently known and available HAT inhibitors with respect to their discovery, further improvements, and current applications.

Novel 1,2,4-thiadiazole derivatives as potent neuroprotectors were synthesized and identified. Their ability to inhibit the glutamate stimulated Ca uptake was measured. Permeation experiments on the phospholipid membranes were conducted, and the apparent permeability coefficients were obtained. The partition coefficients in n-octanol/buffer (pH 7.4) and n-hexane/buffer (pH 7.4) immiscible phases (as model systems for characterizing gastrointestinal tract membranes and BBB) were determined. A classification of the studied compounds from the standpoint of “permeability-activity” properties was proposed.
