C24H26N4O5S : 482.55
[841301-32-4]

Amenamevir is an oral helicase-primase inhibitor launched in 2017 in Japan for the treatment of herpes zoster (shingles). The product is being marketed by Maruho.

Amenamevir had been in phase III clinical trials for herpes simplex virus;

In August 2012, Astellas Pharma granted Maruho development and commercialization rights in Japan.

Patent

JP 2010180169

The publicly known crystal (following and alpha type crystal) of the compound A of disclosure to the aforementioned Patent document 2 is obtained by re-crystallizing from an ethanol water mixed solvent, and has the melting point of about 220 to 222 degree C. The present invention relates to multi-form crystals other than the alpha form crystal concerned, and relates to beta, gamma, delta, and epsilon type crystal specifically. In a surprising thing, each of these multi-form crystals is crystals stable to a degree usable as a medicinal manufacture field object, and has a preferable property in the surface of solubility, absorbency, stability, and/or a handling property
