    Abstract:
    Six acridone alkaloids including a new glycosparvarine (1), three limonoids, and four N-[(4-monoterpenyloxy)phenylethyl]-substituted sulfur-containing propanamide derivatives including two new species, (+)-S-deoxydihydroglyparvin (10) and (+)-S-deoxytetrahydroglyparvin (11), were isolated from the branches and the leaves of Glycosmis parva CRAIB collected in the east of Thailand. Antiviral activity evaluation of isolates against herpes simplex virus (HSV) type 1 and 2 disclosed that two acridone alkaloids, glycosparvarine (1) and glycofolinine (4), showed moderate inhibitory activities with 50% effective concentration (EC50) of 348 microM and 151 microM, respectively; as well, (+)-S-deoxydihydroglyparvin (10) exhibited anti-HSV activity at the lower concentration.
