Phenothiazine and derivatives were tested for inhibition of SARS-CoV replication. Phenothiazine slightly inhibited SARS-CoV replication in a neutral red (NR) uptake assay. Adding a propylamino group to give promazine reduced virus yields (VYR assay) with an EC(90)=8.3+/-2.8 microM, but without selectivity. Various substitutions in the basic phenothiazine structure did not promote efficacy. Phenazine ethosulfate was the most potent compound by VYR assay (EC(90)=6.1+/-4.3 microM). All compounds were toxic (IC(50)=6.6-74.5 microM) except for phenoxathiin (IC(50)=858+/-208 microM) and 10-(alpha-diethylamino-propionyl) phenothiazine.HCl (IC(50)=195+/-71.2 microM). Consequently, none were selective inhibitors of SARS-CoV replication (SI values <1-3.3 microM). These data portended the poor efficacy of promazine in a SARS-CoV mouse lung replication model. Intraperitoneal treatment with promazine using a prophylactic (-4h)/therapeutic regimen of 1, 10, or 50mg/(kg day) did not reduce virus lung titers at day 3, yet prolonged virus replication to 14 days. Similar therapeutic promazine doses were not efficacious. Thus, promazine did not affect SARS-CoV replication in vitro or in vivo, nor were any other phenothiazines efficacious in reducing virus replication. Therefore, treating SARS infections with compounds like promazine is not warranted.
