Abstract:
This study was designed to characterize compounds from two thousands of insects of Blaps japanensis. With this purpose, pipajiains A-C (1-3), three novel phenolic derivatives, pipajiains D (4) and E (5), two new natural occurring compounds, and four known substances were isolated thereof. Their structures were identified by spectroscopic methods. Biological activities of all these compounds towards EV71, tuberculosis, COX-2, ROCK1/2, and JAK3 kinases were evaluated.
