Amide derivative

Abstract

The present invention provides a medicament, in particular, a novel compound for preventing or treating various infections caused by herpesviridae viruses, especially infections caused by various herpes viruses, such as those caused by varicella zoster virus. Varicella (chickenpox), varicella zoster caused by multiple infections of latent varicella-zoster virus, cold sores and herpes encephalitis caused by HSV-1 infection, and genital herpes caused by HSV-2 infection. The present invention provides N-{2-[(4-substituted phenyl)amino]-2-oxoethyl}tetrahydro-2H-thiopyran-4-carbamoyl derivatives and salts thereof, wherein, phenyl The 4-position is substituted by a specific 5- or 6-membered heteroaryl group, it has effective antiviral activity, and it can be administered orally at a low dose to treat the above-mentioned diseases.

Description

technical field [0001] The present invention relates to a novel amide derivative for use as a medicament, especially for the prophylaxis and treatment of diseases involving herpes viruses. Background technique [0002] Viruses of the herpesviridae family cause a wide variety of infectious diseases in humans and animals. For example, it is well known that varicella-zoster virus (VZV) may cause chickenpox and herpes zoster, and herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) may cause infections such as herpes labialis and genital herpes, respectively. In addition, in recent years, infections caused by herpes viruses such as cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human herpesvirus 6, 7, and 8 have also been clarified. [0003] Now, nucleic acid drugs such as acyclovir (ACV) and its prodrugs valacyclovir (VCV) and famciclovir (FCV) are used as drugs against herpes viruses such as VZV and HSV. These nucleic acid drugs are monophosphorylated into nucleoside m...
