Discovery and optimization of tetrahydroacridine derivatives as a novel class of antibiotics against multidrug-resistant Gram-positive pathogens by targeting type I signal peptidase and disrupting bacterial membrane.

Increasing antimicrobial resistance underscores the urgent need for new antibiotics with unique mechanisms. Type I signal peptidase (SPase I) is crucial for bacterial survival and a promising target for antibiotics. Herein we designed and synthesized innovative tetrahydroacridine-9-carboxylic acid derivatives by optimizing the initial hit compound SP11 based on virtual screening.

Discovery of Novel -(Anthracen-9-ylmethyl) Benzamide Derivatives as ZNF207 Inhibitors Promising in Treating Glioma.

Targeting tumor stemness is an innovative approach to cancer treatment. Zinc Finger Protein 207 (ZNF207) is a promising target for weakening the stemness of glioma cells. Here, a series of novel -(anthracen-9-ylmethyl) benzamide derivatives against ZNF207 were rationally designed and synthesized.

Novel dual-target μ‑opioid and TRPV1 ligands as potential pharmacotherapeutics for pain management.

Currently, the development of effective analgesic drugs with few side effects remains a great challenge. Studies have suggested that multi-target drug treatments show high efficacy and reduced side effects compared to single-target drug therapies. In this work, we designed and synthesized two series of novel MOR/TRPV1 dual active ligands in which the phenylpiperidine group or the N-phenyl-N-(piperidin-4-yl) propionamide group as the MOR pharmacophore was fused to the benzylpiperazinyl urea-based TRPV1 pharmacophore.

Novel piperazine urea derivatives as highly potent transient receptor potential vanilloid 1 (TRPV1) antagonists.

Transient receptor potential vanilloid 1 (TRPV1) is a non-selective cation channel with high permeability to Ca, which can be activated by low pH, noxious heat and vanilloid compounds such as capsaicin. TRPV1 has been proved to be very important in the process of pain production and is considered to be a highly effective analgesic target. In this work, three series of new piperazine urea TRPV1 antagonists were designed, synthesized and evaluated based on classical TRPV1 antagonists BCTC and GRT12360.

A patent review of transient receptor potential vanilloid type 1 modulators (2014-present).

: Transient receptor potential vanilloid 1 (TRPV1) is a nonselective cation channel with high permeability to calcium, which is widely expressed in the central nervous system (CNS) and peripheral nervous system. Since the TRPV1 was molecularly cloned more than 20 years ago, a series of research activities have been carried out on the possibility of new drugs. : This review summarizes the patents on TRPV1 regulators (including agonists and antagonists) that were published during 2014-present and predicts the development direction in the future.

Study on chemical modification and analgesic activity of N-(4-tert-butylphenyl)-4-(3-chloropyridin-2-yl) piperazine-1-carboxamide.

N-(4-Tert-butylphenyl)-4-(3-chloropyridin-2-yl) piperazine-1-carboxamide (BCTC) is a potent and extensively studied urea-based TRPV1 antagonist. Although BCTC was effective in alleviating chronic pain in rats, it showed obvious hyperthermia side-effect and unsatisfactory pharmacokinetic profile, therefore, it was not developed further. In order to enrich the structural types of urea-based TRPV1 antagonists, two series of novel analogs, in which the pyridine ring of BCTC was replaced with a mildly basic pyrimidine ring or 1,2,3,4-tetrahydro-β-carboline scaffold, were designed and synthesized.
