The disclosure demonstrates the inhibition of replication of human cytomegalovirus (HCMV) in cultured human embryo skin muscle cells by two separate subclasses of direct-acting smooth muscle relaxing agents alone or in combination with each other. These two subclasses are characterized mechanistically as calcium influx blockers (or calcium channel blockers) and cyclic nucleotide modulators. More specifically, the class of calcium influx blockers is exemplified by the drugs verapamil (and methoxyverapamil), nifedipine (the prototype drug of 1,4 dihydropyridines), and diltiazem. The class of cyclic nucleotide modulators is exemplified by the drugs isobutylmethlyxanthine, papaverine (and its synthetic analog dioxyline), forskolin, and sodium nitroprusside. In addition, the present disclosure demonstrates that agents from one class, e.g., a calcium influx blocker, act synergistically when used in combination with agents from the other class, e.g., cyclic nucleotide modulators. Moreover, the calcium influx blockers are shown to act synergistically when used in combination with alpha interferon.
