體外研究

L-732138 (0 -100 μM; first doubling time; COLO 858, MEL HO and COLO 679 cells) treatment results in a concentration-dependent cytotoxicity. L-732138 inhibits cell growth with IC 50 of 44.6 μM for COLO 858 cells, 76.3 μM for MEL HO cells and 64.2 μM for COLO 679 cells. L-732138 blocks substance P (SP) mitogen stimulation.
L-732,138 treatment results in a large number of apoptotic cells were found in COLO 858, MEL HO and COLO 679 melanoma cell lines. In DAPI-stained cultures, at IC 50 concentration of 43.6% apoptotic cells for the three melanoma cell lines, whereas at IC 100 concentration of 51.4 % apoptotic cells.

Cell Proliferation Assay

Cell Line: COLO 858, MEL HO and COLO 679 cells
Concentration: 0 μM, 20 μM, 40 μM, 60 μM, 80 μM, 100 μM
Incubation Time: First doubling time
Result: Resulted in a concentration-dependent cytotoxicity.
體內(nèi)研究

L-732138 (10 -4 -10 -2 mol/kg; intravenous injection; for 15 minutes; male Dunkin-Hartley guinea-pigs) treatment abolishes vagally-induced plasma exudation and significantly inhibits the enhancement by LPS. The LPS-enhanced vagally-induced plasma exudation is not completely inhibited by either L-732138 or SOD pretreatment alone, but is blocked by the combination of both pretreatments.

Animal Model: Male Dunkin-Hartley guinea-pigs (350-500 g) injected with lipopolysaccharide (LPS)
Dosage: 10 -4 mol/kg , 10 -3 mol/kg and 10 -2 mol/kg
Administration: Intravenous injection; for 15 minutes
Result: Abolished the vagally-induced plasma leakage in tracheobronchial tissues, and dose-dependently inhibited the LPS enhanced vagally-induced plasma exudation in traceobronchial tissues.
