Docking assisted design of novel 4-adamantanyl-2-thiazolylimino-5-arylidene-4-thiazolidinones as potent NSAIDs$

Docking analysis was used to predict the effectiveness of adamantanyl insertion in improving cycloxygenase/lipoxygenase (COX/LOX) inhibitory action of previously tested 2-thiazolylimino-5-arylidene-4-thiazolidinones. The crystal structure data of human 5-LOX (3O8Y), ovine COX-1 (1EQH) and mouse COX-2 (3ln1) were used for docking analysis. All docking calculations were carried out using AutoDock 4.2 software. Following prediction results, 11 adamantanyl derivatives were synthesized and evaluated for biological action. Prediction evaluations correlated well with experimental biological results. Comparison of the novel adamantanyl derivatives with the 2-thiazolylimino-5-arylidene-4-thiazolidinones previously tested showed that insertion of the adamantanyl group led to the production of more potent COX-1 inhibitors, as well as LOX inhibitors (increased activity from 200% to 560%). Five compounds out of the 11 exhibited better activity than naproxen; while nine out of 11 showed better activity than NDGA and seven compounds possessed better anti-inflammatory activity than indomethacin.

(+)-Biotin: A Challenge for industrially viable total synthesis of natural products

The course of our investigation to develop an industrially viable total synthesis of (+)-biotin is described. Three synthetic approaches to (+)-biotin have been investigated to develop an efficient synthetic method using L-cysteine and thiolactone as a starting material and a key intermediate, respectively. Short steps, high yield and ease of operation of the approach would permit the hitherto most efficient access to (+)-biotin.

The bromodomain: From epigenome reader to druggable target

Lysine acetylation is a fundamental post-translational modification that plays an important role in the control of gene transcription in chromatin in an ordered fashion. The bromodomain, the conserved structural module present in transcription-associated proteins, functions exclusively to recognize acetyl-lysine on histones and non-histone proteins. The structural analyses of bromodomains’ recognition of lysine-acetylated peptides derived from histones and cellular proteins provide detailed insights into the differences and unifying features of biological ligand binding selectivity by the bromodomains. Newly developed small-molecule inhibitors targeting bromodomain proteins further highlight the functional importance of bromodomain/acetyl-lysine binding as a key mechanism in orchestrating molecular interactions and regulation in chromatin biology and gene transcription. These new studies argue that modulating bromodomain/acetyl-lysine interactions with small-molecule chemicals offer new opportunities to control gene expression in a wide array of human diseases including cancer and inflammation. This article is part of a Special Issue entitled: Molecular mechanisms of histone modification function.

An update on chemical classes targeting ERK1/2 for the management of cancer

Cancer, still in the limelight due to its dreadful nature, shows overexpression of multiple signaling macromolecules leading to failure of many chemotherapeutic agents and acquired resistance to chemotherapy. These factors highlight the significance of shifting toward targeted therapy in cancer research. Recently, ERKs (ERK1 and 2) have been established as a promising target for the management of various types of solid tumors, due to their aberrant involvement in cell growth and progression. Several ERKs inhibitors have reached clinical trials for the management of cancer and their derivatives are being continuously reported with noteworthy anticancer effect. This review highlights the recent reports on various chemical classes involved in the development of ERKs inhibitors along with their in vitro and in vivo activity and structure-activity relationship profile.

Design, synthesis and in-silico study of novel series of 2-phenyl- 3-(5-sulfanyl-1,3,4-thiadiazol-2-yl)-1,3-thiazolidin-4-one derivatives with potential anti-tubercular activity

In an attempt to identify potential new agents active against tuberculosis with Shikimate kinase as the target, a novel series of 2-phenyl- 3-(5-sulfanyl-1,3,4-thiadiazol-2-yl)-1,3-thiazolidin-4-one derivatives were synthesized by convenient one-pot three-component reaction of amine, aldehyde and mercaptoacetic acid on montmorillonite KSF clay as a solid acidic catalyst in good yields. The structures of the newly synthesized compounds were confirmed by IR, 1H-NMR and elemental analysis and were subjected for anti-tubercular activity by Microplate Alamar Blue Assay (MABA) against Mycobacterium tuberculosis H37Rv. Docking and ADMET studies were used to better describe the titled compounds as potential anti-tubercular agents. The compound, 2-(3,4-dimethoxyphenyl)-3-(5-sulfanyl-1,3,4-thiadiazol-2-yl)-1,3-thiazolidin-4-one(4j), was found to be the most active against Mycobacterium tuberculosis H37Rv with MIC of 1.6 mug/ml and good drug likeness and dock scores. Molecular docking study revealed that the molecules fit well into the cavity of Shikimate kinase. Also, the molecular properties and bioactivity scores for the synthesized compounds obtained by in-silico studies were found to be within the acceptable range defined for human use revealing their potential as possible drug-like compounds. The anti-tubercular activity of the titled compounds was comparable to that of the standard drug Isoniazid and Ciprofloxacin. The results indicate that the synthesized thiadiazolyl-thiazolidinone derivatives may have an affinity towards Shikimate kinase active site which can be further explored for selective target based studies. Thus these compounds could act as a potential lead for further anti-tubercular studies.
