Sebum is produced by the sebaceous glands located alongside hair follicles. Mature sebocytes accumulate lipid droplets in their cytoplasm and subsequently release their contents through holocrine secretion. Sebum mainly contains triglycerides and their breakdown products, wax esters, squalene, ...
Indazole is a nitrogen-containing aromatic heterocycle formed by the fusion of a benzene ring with a pyrazole ring. Its value in medicinal chemistry does not lie merely in the fact that it “contains two nitrogen atoms” or that “a variety of biological activities have been reported.” ...
7-Azaindole consists of a fused pyridine and pyrrole ring system. Compared with conventional indole, one carbon atom in the six-membered aromatic ring is replaced by a nitrogen atom, resulting in changes in the molecular electron distribution, basicity, and hydrogen-bonding behavior. ...
The traditional Chinese medicinal material Longdan consists of the dried roots and rhizomes of plants in the Gentianaceae family, including Gentiana manshurica, Gentiana scabra, Gentiana triflora, and Gentiana rigescens.
The CEACAM family participates in epithelial homeostasis through cell adhesion, receptor signaling, and immune regulation. CEACAM5 and CEACAM6 are aberrantly overexpressed in multiple solid tumors and provide important targets for tumor biomarkers, antibody-drug conjugates, and cellular ...
Under the combined constraints of “aryl/heteroaryl chlorides (Ar–Cl) + low Pd loading + scale-up reproducibility,” the most common source of instability does not necessarily show up as “a complicated mechanism,” but rather as a more straightforward engineering issue: whether the mode ...
β-Galactosidase (β-galactosidase, EC 3.2.1.23) is a glycoside hydrolase family that catalyzes hydrolysis of β-D-galactosidic bonds. It can cleave lactose and related substrates into monosaccharides and, under certain conditions, carry out transgalactosylation to generate products such as ...
β-Lactamases are a family of enzymes that hydrolyze the β-lactam ring and inactivate β-lactam antibacterial agents, constituting a major molecular basis for acquired bacterial resistance. β-Lactam antibiotics primarily target penicillin-binding proteins (PBPs) and disrupt peptidoglycan ...
α-Amylase (α-amylase) is a class of glycoside hydrolases widely distributed in animals, plants, and microorganisms. Acting in an endo-fashion, it catalyzes cleavage of α-1,4-glycosidic bonds in starch, glycogen, and related α-1,4-glucans, generating products such as maltose, maltotriose, and ...
