thebaine/悪性腫瘍

Buprenorphine (BUP) is a semisynthetic derivative of the opium alkaloid thebaine found in the poppy Papaver somniferum. Its chemical structure contains the morphine structure but differs by having a cyclopropylmethyl group. Buprenorphine is a potent µ opioid agonist. Buprenorphine undergoes

In screening cytotoxic agents in morphine alkaloids [TE1-10], codeinone [TE8] was cytotoxic against two human oral tumor cells lines (HSC-2 and HSG). The cytotoxic activity of codeinone (CC50=1.0-1.2 microg/mL) against HSC-2 or HSG cells was higher than that of doxorubicin (CC50=1.9-2.0 microg/mL).

Alkaloids represent a large and diverse group of compounds that are related by the occurrence of a nitrogen atom within a heterocyclic backbone. Unlike other types of secondary metabolites, the various structural categories of alkaloids are unrelated in terms of biosynthesis and evolution. Although

Background: Buprenorphine (BUP) a "synthetic derivative of the opioid alkaloid thebaine" may be associated with cellular damage in the central nervous system. Aims: This study

The perpetual pursuit of pain elimination has been constant throughout human history and pervades human cultures. In some ways it is as old as medicine itself. Cultures throughout history have practiced the art of pain management through remedies such as oral ingestion of herbs or techniques
