Disease relevance of NSC54677


High impact information on NSC54677

  • SR233377 is a novel thioxanthenone analogue that demonstrated solid tumor selectivity in vitro with activity confirmed in vivo against several murine tumors including those of colon, pancreas, and mammary origin [4].
  • We investigated the mechanism of DNA damage induced by photoexcited xanthone (XAN) analogues (XAN, thioxanthone [TXAN] and acridone [ACR]), exogenous photosensitizers, and the relationship between the DNA-damaging abilities and their highest occupied molecular orbital (HOMO) energies [5].
  • PURPOSE: SR233377 (WIN33377) is a novel 4-aminomethyl thioxanthone derivative with promising preclinical activity against solid tumors at doses substantially below the MTD [6].
  • Two other photoinitiators, Michler's ketone and thioxanthone were phototoxic in vitro but not after topical application in vivo [7].

Analytical, diagnostic and therapeutic context of NSC54677

  • A simple and reliable HPLC method was developed for the estimation of a new anti-cancer agent that belongs to the thioxanthone class, SR271425 in mouse plasma [8].
