Molecular hybridization approach was used to synthesize substituted 2-(2-(4-aryl oxy benzylidene) hydrazinyl)benzo thiazole derivatives with 2-hydrazinobenzothiazole and 4-(alicycli/aryl/biaryl/heteroaryl oxy)benzaldehyde as new anti-TB agents. The synthesized compounds, when tested against H37Rv strains of Mtb using Resazurin Microtitre Assay (REMA) method, showed promising activity (MIC 1.35-36.50 μg/mL). 6-chloro-2-(2-(4- (pyridin-4-yloxy) benzylidene) hydrazinyl) benzo[d]thiazole (10v) gave MIC of 1.35 μg/mL. Thus making it, a potential lead could be developed for further antitubercular studies.

Tyrosine-protein kinase Src plays a key role in cell proliferation and growth under favorable conditions, but its overexpression and genetic mutations can lead to the progression of various inflammatory diseases. Due to the specificity and selectivity problems of previously discovered inhibitors like dasatinib and bosutinib, we employed an integrated machine learning and structure-based drug repurposing strategy to find novel, targeted, and non-toxic Src kinase inhibitors. Different machine learning models including random forest (RF), k-nearest neighbors (K-NN), decision tree, and support vector machine (SVM), were trained using already available bioactivity data of Src kinase targeting compounds.

Herein, we report the synthesis of a series of new compounds by combining 2-aminobenzothiazole with various profens. The compounds were characterized using techniques such as H- and C-NMR, FT-IR spectrometry, and high-resolution mass spectrometry (HRMS), with detailed HRMS analysis conducted for each molecule. Their biological activities were tested in vitro, revealing significant anti-inflammatory and antioxidant effects, comparable to those of standard reference compounds.

Hydrogen-bonded organic framework (HOF) materials are typically formed by the self-assembly of small organic units (synthons) with specific functional groups through hydrogen bonding or other interactions. HOF is commonly used as an electrolyte for batteries. Well-designed HOF materials can enhance the proton exchange rate, thereby boosting battery performance.
