L-733060 hydrochloride is a potent tachykinin NK1 receptor antagonist. L-733060 hydrochloride inhibits neurogenic plasma extravasation at doses that do not cause adverse cardiovascular effects in rodents and also acts as an antitumoral agent[1][2].

IC50 & Target[1]



(In Vitro)

L-733060 (30-300 nM) inhibits the [Ca2+]i mobilisation caused by substance P (100 nM) in a concentration-dependent manner in human tachykinin NK1 receptor-transfected CHO cells[1].
L-733060 (2.5-20 μM; 48 and or 96 h) results in a concentration-dependent cytotoxicity in COLO 858 cells[2].
L-733060 (10-30 μM; 24 and 48 h) inhibits MEL H0 cells proliferation with IC50s of 27.5 μM and 18.9 μM at 24 h and 48 h, respectively[2].
L-733060 (20-50 μM; and or 72 h) inhibits COLO 679 cells growth with IC50s of 33.8 μM and 31.5 μM at 30 h and 72 h, respectively[2].

Cell Proliferation Assay[2]

Cell Line: COLO 858 cells
Concentration: 2.5, 5, 10, 20 μM
Incubation Time: 0, 48, 96 h
Result: Inhibited cells growth with IC50s of 8.7 μM and 7.1 μM at 48 h and 96 h, respectively.

(In Vivo)

L-733060 (10-1000 μg/kg; i.v.) inhibits electrically stimulated plasma extravasation in dura mater of rats[1].
L-733060 (300-3000 μg/kg; i.v.) has no significant hypotensive or bradycardic effects are observed at doses of <3000 μg>[1].

上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Sprague-Dawley rats (200 g) with electrical stimulation of the trigeminal ganglion[1]
Dosage: 10, 100, 1000 mg/kg
Administration: I.v. injection
Result: Produced a significant dose-related inhibition of plasma extravasation with an ID50 of 212±19 μg/kg.
