Hydroxylamine 175-184 RA25 Homo sapiens 15-19 8810098-3 1996 The binding constants for the neutral drug forms change in the same order in the range of 1400-3100 M-1 for DIP to 80-300 M-1 for RA25. Dipyridamole 108-111 RA25 Homo sapiens 130-134 18028212-3 2007 In the present work, the quenching of singlet molecular oxygen, O(2)((1)Delta(g)), by DIP and RA47 and RA25 derivatives was analyzed in acetonitrile (ACN) and aqueous acid solutions.
