Selective and synergistic inhibition of human immunodeficiency virus type 1 reverse transcriptase by a non-nucleoside inhibitor, MKC-442.

abstract：:Carbachol is 100 times more potent for inhibiting cyclic AMP formation than for stimulating phosphoinositide (PI) hydrolysis in chick heart cells. To determine whether this reflects differences in agonist affinity of the receptor(s) coupled to the two responses, we measured these functional responses following removal...
