hERG is best known as a primary anti-target, the inhibition of which is responsible for serious side effects. A renewed interest in hERG as a desired target, especially in oncology, was sparked because of its role in cellular proliferation and apoptosis. In this study, we survey the most recent advances regarding hERG by focusing on SAR in the attempt to elucidate, at a molecular level, off-target and on-target actions of potential hERG binders, which are highly promiscuous and largely varying in structure. Understanding the rationale behind hERG interactions and the molecular determinants of hERG activity is a real challenge and comprehension of this is of the utmost importance to prioritize compounds in early stages of drug discovery and to minimize cardiotoxicity attrition in preclinical and clinical studies.

The worldwide occurrence of neurodegenerative diseases in Alzheimer's and Parkinson's patients is increasing owing to multiple disease mechanisms, including oxidative stress, neuroinflammation, mitochondrial dysfunction, and excitotoxicity. (clove) flavonoid metabolites show strong neuroprotective potential because they act as antioxidants, reduce inflammation and lipid peroxidation, and prevent apoptosis. The key flavonoid metabolites, quercetin, kaempferol, kumatakenin, myricetin, ombuin 3-O-β-d-glucopyranoside, and tamarixetin 3-O-β-d-glucopyranoside, bind to various brain receptors implicated in disease propagation pathways and induce changes that support neuronal survival and decrease cognitive impairment.

Sclerostin, a key regulator of Wnt/β-catenin signaling, exhibits dual therapeutic potential in bone disorders: its inhibition promotes bone formation in osteoporosis, while its mimicry suppresses aberrant bone growth in osteoarthritis (OA). Using structural insights from NMR studies, we identified two sclerostin-derived peptides: SC-1 (an 18-mer) from loop 2, and SC-3 (a 14-mer) from loop 3. Molecular modeling showed that SC-1 binds to the first ectodomain of LRP6, potentially displacing sclerostin through competitive inhibition to activate Wnt signaling.

Background: Women are under-represented in cardiovascular research, leading to poorer outcomes. Investigating sex-differences in electromechanical function is essential for improving therapy evaluation. This study presents sex-specific human cellular and biventricular electromechanical models for mechanistic investigation of sex-differences in therapeutic response.

This study aimed to identify ideal pharmaceutical candidates featuring strong anti-HIV-1 activity and desirable drug-like characteristics. Our endeavor involved the implementation of a bioisosterism strategy, leading to the discovery of an assemblage of halogen-containing biphenyl-diarylpyrimidines as potent HIV-1 non-nucleoside reverse transcriptase inhibitors. Notably, compound demonstrated exceptional efficacy against both WT HIV-1 (EC = 1.

Unlabelled: The aim of this work is the synthesis of nine coumarin-hydrazone derivatives and their characterization by IR, 1D NMR, 2D NMR, NOESY, and elemental analysis, as well as the evaluation of their antiplatelet activity through in vitro and in silico tests. Among the tested series, compounds and showed significant inhibition of ADP-induced platelet aggregation, by 87% and 98%, respectively. Notably, compound completely inhibited arachidonic acid-induced aggregation, while none of the molecules affected the collagen pathway.
