The metalloproteinase ADAM10 has been reported as an important target for drug discovery in several human diseases. In this vein, (6,7)--hydroxy-5-methyl-6-(4-(5-(trifluoromethyl)pyridin-2-yl)piperazine-1-carbonyl)-5-azaspiro[2.5]octane-7-carboxamide (compound ) has been reported as a selective ADAM10 inhibitor. We synthesized this compound and document that it lacks both potency and selectivity in inhibition of ADAM10. This finding necessitated a structure-based computational analysis to investigate potency and selectivity of ADAM10 inhibition. The model that emerged indeed excluded compound as an inhibitor for ADAM10, while suggesting another reported compound, (1,3,4)-3-(hydroxycarbamoyl)-4-(4-phenylpiperidine-1-carbonyl)cyclohexyl pyrrolidine-1-carboxylate (compound ), as an ADAM10 selective inhibitor. Compound was synthesized and its potency, and selectivity in inhibition of ADAM10 were documented with a panel of several related enzymes. Pharmacokinetic studies of compound in mice documented that the compound crosses the blood-brain barrier and may be useful as a pharmacological agent or mechanistic tool to delineate the role of ADAM10 in neurological diseases.

Chronic kidney disease (CKD) is a major complication of type 2 diabetes mellitus (T2D), which often leads to diabetic kidney disease (DKD). Traditional therapies, including renin- angiotensin-aldosterone system inhibitors and sodium-glucose cotransporter-2 inhibitors, are effective in slowing CKD progression. However, these approaches are insufficient to comprehensively inhibit mineralocorticoid receptor (MR) overactivation in the kidneys, which remains a significant driver of inflammation, fibrosis, and oxidative stress.

Introduction: Neuroinflammation derived from the activation of the microglia is considered a vital pathogenic factor of Alzheimer's Disease (AD). T-006, a tetramethylpyrazine derivative, has been found to alleviate cognitive deficits via inhibiting tau expression and phosphorylation in AD transgenic mouse models. Recently, T-006 has been proven to dramatically decrease the levels of total Amyloid β (Aβ) peptide and Glial Fibrillary Acidic Protein (GFAP) and suppress the expression of ionized calcium binding adaptor molecule-1 (Iba-1) in APP/PS1 mice.

Considering the multifactorial and complex nature of Alzheimer's disease and the requirement of an optimum multifunctional anti-Alzheimer's agent, a series of triazole tethered coumarin-eugenol hybrid molecules was designed as potential multifunctional anti-Alzheimer's agents using donepezil and a template. The designed hybrid molecules were synthesized a click chemistry approach and preliminarily screened for cholinesterase and Aβ aggregation inhibition. Among them, AS15 emerged as a selective inhibitor of AChE (IC = 0.

Many cancers have displayed resistance to chemotherapeutic drugs over the past few decades. EGFR has emerged as a leading target for cancer therapy inhibiting tumor angiogenesis. Besides, studies strongly suggest that blocking telomerase activity could be an effective way to control the growth of certain cancer cells.
