4"- (2- (p-Chlorophenyl) acetoxyl) spiramycin

4"- (2- (p-Chlorophenyl) acetoxyl) spiramycin (Compound 2d) is a broad-spectrum anti-coronaviral agent via targeting frameshifting element (FSE) . 4"- (2- (p-Chlorophenyl) acetoxyl) spiramycin inhibits HCoV-OC43 and HCoV-229E with EC50 values of 0.85 μM and 1.45 μM. 4"- (2- (p-Chlorophenyl) acetoxyl) spiramycin shows a dual-target mechanism that acts on both viral FSE RNA and host DIS3L2[1].
