生物活性

Levocabastine (R 50547) is a potent and selective histamine H1-receptor antagonist. Levocabastine hydrochloride is also a selective, high affinity neurotensin receptor subtype 2 (NTR2) antagonist, with a Ki of 17 nM for mNTR2. Levocabastine can act as a VLA-4 antagonist, interferes with conjunctival eosinophil infiltration in allergic conjunctivitis (AC)[1][2][3].

体外研究
(In Vitro)

Levocabastine (0-1000 μM; HEK-293 cells) causes inhibition of 125I-FN binding to the SPA bead-associated α4β1 integrin in a concentration-dependent manner with an IC50 of 406.2μm[3].
Levocabastine (0-1000 μM; 30 min; Jurkat cells and EoL-1 cells) inhibits α4β1 integrin/VCAM-1-mediated cell adhesion in vitro. Levocabastine inhibits α4β1 integrindependent adhesion of Jurkat cells to VCAM-1 with an IC50 of 395.6 μM, and the adhesion of EoL-1 cells with an IC50 of 403.6 μM. Moreover, Levocabastine inhibits adhesion of human eosinophils to VCAM-1-coated wells (IC50=443.7 μM)[3].

(In Vivo)

Levocabastine (R 50547; 0.25 mg/kg; i.p.; twice a day for five days; guinea-pig with Parainfluenza-3 (PI-3) virus) inhibits the virus-induced airway hyperresponsiveness[1].
Levocabastine (0.05 mg/kg; i.p.; once; male C57BL/6J mice) blocks anti-stress effect ofβ-LT on mouse behavior[2].
Levocabastine (500 µg/eye; drops eye; once; ovalbumin-sensitized guinea pigs) induces allergic conjunctivitis (AC) and a significant increase of conjunctival VLA-4[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Guinea-pig with Parainfluenza-3 (PI-3) virus[1]
Dosage: 0.25 mg/kg
Administration: Intraperitoneal injection; twice a day for five days
Result: Suppressed the influx of broncho-alveolar cells and increased in albumin content.
Animal Model: Male C57BL/6J mice (8-9 weeks old)[2]
Dosage: 0.05 mg/kg; 30 mg/kg (β-LT)
Administration: Intraperitoneal injection; once
Result: Blocked the anxiolytic effect of β-LT and decreased the number of head-dips.
Animal Model: Ovalbumin-sensitized guinea pigs[3]
Dosage: 500 µg/eye
Administration: drops eye, once
Result: Produced a noteworthy protection from allergic conjunctivitis (AC) and prevented the conjuctival elevation of VLA-4 as well as conjunctival eosinophil infiltration.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
