Potential antitumor agents. 37. Organophosphorus derivatives of 9-anilinoacridine
摘要:
A series of 9-anilinoacridine derivatives substituted in the anilino ring with a variety of phosphoramide and related substitutents has been prepared, and the antitumor activity has been evaluated both in vivo and in vitro against the L1210 or P-388 mouse leukemia systems. The DNA-binding properties were measured using the ethidium displacement method, and the structural requirements for strong binding were found to differ from those for antileukemic activity. For high biological activity a marked preference for oxygen-containing substituents on the phosphorus atom was noted, while for high DNA binding a requirement for nitrogen-containing or cyclized substituents was observed. The most active congeners, as assayed in both in vitro and in vivo systems, were comparable in activity to the clinically utilized anilinoacridine derivative N-[4'-(9-acridinylamino)-3'-methoxyphenyl]methanesulfonamide (m-AMSA, amsacrine).

A visible‐light‐inducedmetal‐free catalytic system was developed for the synthesis of arylphosphonates starting from arylhydrazines and trialkylphosphites. By using the inexpensive eosin B as catalyst, sub‐stoichiometric amounts of DABCO, and ambient air as oxidant, diverse arylphosphonates were obtained under visible‐light irradiation. Notably, this catalytic system is suitable for gram‐scale reaction
Aniline derivatives were phosphorylated in biphase systems using three methods. A comparative study was performed. The best results were obtained when a solid-liquid system was used. This method is the easiest and lead to higher yields (54-81%).
