Synonyms: REGN-5381
Vixticibart (REGN-5381) is a fully human IgG4 monoclonal antibody and NPR1 agonist that targets NPR1. Vixticibart stabilizes the receptor in an activated conformation by binding to the N-terminal domain of NPR1, and enhances the activity of endogenous ligands ANP and BNP without blocking ligand binding when these ligands are present. Vixticibart exerts vasodilatory and hypotensive effects by inducing cGMP production, preferentially dilating venous vessels to reduce systolic and venous pressure, but does not induce diuresis and may trigger a compensatory increase in heart rate. Vixticibart produces a synergistic hypotensive effect when combined with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, and is currently mainly used in research related to heart failure and hypertension .

Metabolic Disease

HPTE is the active in vivo metabolite of Methoxychlor (HY-B1873), and acts as an inhibitor of 3β‑HSD and 17β‑HSD3. HPTE binds to the substrate-binding pocket of 3β‑HSD in a non-competitive manner, but competitively occupies the coenzyme NAD +-binding site, thereby inhibiting the conversion of pregnenolone to progesterone. HPTE binds to the androstenedione-binding pocket (the substrate pocket) of 17β‑HSD3 in a non-competitive manner, and competitively occupies the coenzyme NADPH-binding site, thus blocking the conversion of androstenedione to testosterone. HPTE interferes with androgen biosynthesis in Leydig cells by inhibiting the activities of these two key steroidogenic enzymes. HPTE can be used in studies related to androgen biosynthesis .

Kinases are enzymes that catalyze the addition of phosphate groups to substrate molecules, a process known as phosphorylation. Protein phosphorylation serves as a critical regulatory mechanism for numerous cellular processes, including cell division, metabolism, and signal transduction. The human genome encodes over 500 kinases, which collectively regulate approximately 50% of cellular functions. Due to their pivotal roles, kinases represent one of the most important target classes in drug development.

Kinase inhibitors can selectively block the activity of disease-associated kinases, making them valuable therapeutics for conditions such as cancer and inflammatory diseases. FDA-approved kinase inhibitors have undergone extensive preclinical and clinical studies, demonstrating high bioactivity, favorable safety profiles, and good bioavailability, rendering them suitable for investigating new therapeutic indications.

Tyrostatin is a peptide inhibitor isolated from Kitasatospora sp. 55. It has a Ki value of 6 nM against serine carboxyl protease (PSCP) from Pseudomonas sp. 101, a Ki value of 2.1 nM against carboxyl protease (XSCP) from Xanthomonas sp. T-22, and a Ki value of 2.6 nM against carboxyl protease (PCP) from Pseudomonas sp. 101. Tyrostatin forms a reversible covalent hemiacetal bond with Ser287 at the active site of PSCP, where Tyr at the P1 position and Leu at the P2 position occupy the S1-S4 subsites of the enzyme. Tyrostatin inhibits the activity of XSCP, specifically blocks the autocatalytic maturation process of PCP precursor under acidic conditions, and also inhibits the protease activity of mature and recombinant PCP in a dose-dependent manner. Tyrostatin does not inhibit KSCP or alcohol-resistant protease J-4, and can serve as a tool for identifying the catalytic residues of PCP .
