Amitriptyline is an orally active tricyclic antidepressant (TCA). Amitriptyline mainly exerts its antidepressant effect by blocking SERT (Ki = 3.45 nM) and NET (Ki = 13.3 nM), thereby increasing the concentrations of 5-hydroxytryptamine (5-HT) and norepinephrine (NE) in the synaptic cleft. Amitriptyline is also an agonist at α2A and TrkA/TrkB receptors, thereby exerting analgesic and neurotrophic activities (inhibiting cell apoptosis). Amitriptyline can reduce inflammation, angiogenesis and fibrosis. Amitriptyline binds to DAT (with Ki = 2.58 μM). Amitriptyline has high affinity for a series of receptors and can antagonize muscarinic cholinergic receptors (M1/M2/M3/M4/M5 receptors) (Ki = 11-24 nM), H1 receptors (Ki = 0.5-1.1 nM), adrenergic α1 receptors (Ki = 4.4 nM), etc., resulting in a series of side effects. Amitriptyline can block sodium channels and hERG potassium channel (IC50 = 4.78 μM) and it has cardiotoxicity .

Quinine hydrochloride is an alkaloid extracted from cinchona bark and exhibits oral activity, acting as a potassium channel inhibitor. Quinine hydrochloride modulates the tolerance of red blood cells and presents dose-dependent toxicity and embryonic effects. Quinine hydrochloride is a typical hemolysin that directly lyses red blood cells, with cellular components of red blood cell membranes as its action targets. Quinine hydrochloride disrupts red blood cell membranes and induces hemolysis at high concentrations, while merely weakening the anti-hemolytic capacity of red blood cells at low concentrations. Quinine hydrochloride continuously reduces red blood cell tolerance after in vivo administration, and high doses can also alter blood cell counts. Quinine hydrochloride can be applied to researches related to red blood cell hemolysis, cancer and malaria .

DQ-BSA-Red is a bovine serum albumin labeled with a red fluorescent dye that can be used to detect lysosomal activity. The excitation wavelength and emission wavelength of DQ-BSA-Red are 590 nm and 620 nm, respectively. The BSA molecule in DQ-BSA-Red is labeled with high concentration of red fluorescent dye in multiple sites, which shows high fluorescence self-inhibition. Once DQ-BSA-RED enters the lysosome, DQ-BSA is cleaved by lysosomal proteases, resulting in unquenched and released fluorescent fragments, emitting bright fluorescence. Inactivated lysosomes are unable to degrade the BSA protein and thus have a lower or even no fluorescent signal .

Ser/Thr Protease

Research Areas:  

Inflammation/Immunology

Benzamidine is a competitive protease inhibitor that blocks the hydrolytic cleavage of glucagon by plasmin, trypsin and thrombin. Benzamidine effectively inhibits the degradation of glucagon by relevant proteases during the collection, storage and analysis of human plasma and blood samples. During in vivo metabolism, Benzamidine undergoes N-hydroxylation and produces multiple metabolites, exhibiting characteristics of delayed excretion or biphasic elimination. Benzamidine only induces slight single-strand DNA breaks at high concentrations and shows no significant genotoxic potential overall. Benzamidine may interfere with the detection of some glucagon antisera, but does not affect key antigen-antibody affinity at specific concentrations. Benzamidine can be used as a stabilizer in glucagon radioimmunoassays to ensure the accuracy and recovery rate of detection results .
