 Use of GS 6201


GS-6201 (CVT-6883) is a selective adenosine A2B receptor antagonist. GS-6201 displays high affinity and selectivity for the human adenosine A2B receptors (Ki=22 nM)[1]. GS-6201 reduces caspase-1 activity in the heart, and attenuates cardiac remodeling after acute myocardial infarction (AMI) in the mouse[2]. GS-62013 attenuates the airway reactivity induced by NECA, AMP, or allergen in sensitized mice[3].

In Vivo GS-6201 (CVT-6883) (4 mg/kg; i.p.; every 12 h for 14 days) significantly reduces IL-6, TNF-α, E-selectin, ICAM-1, and VCAM plasma levels[2]. GS-6201 (4 mg/kg; i.p.; every 12 h for 14 days) leads to a significant attenuation of left and right ventricular enlargement and dysfunction at 7 days, which was maintained at 14 days and also at 28 days[2]. GS-6201 (2 mg/kg; p.o.) treatment shows the Cmax, dAUC and t1/2 are 1110 ng/mL, 6500 ng h/mL, and 4.25 hours, respectively[1]. Animal Model: Adult out-bred male CD1 mice (8-12 weeks of age, AMI model)[2] Dosage: 4 mg/kg Administration: i.p.; every 12 h for 14 days Result: Significantly reduced IL-6, TNF-α, E-selectin, ICAM-1, and VCAM plasma levels. Animal Model: Sprague-Dawley rats[1] Dosage: 2 mg/kg Administration: p.o. (Pharmacokinetic Analysis) Result: The Cmax, dAUC and t1/2 were 1110 ng/mL, 6500 ng h/mL, and 4.25 hours, respectively.
