“…11 Subsequently, the study on tryptanthrin alkaloid was discussed in another review article in 2013, where various synthetic methods were applied for the preparation of tryptanthrin. 12a Owing to its pharmacologically aromatic indoloquinazoline moiety with a wide range of biological and pharmacological activities, tryptanthrin has been extensively applied as a parental backbone via the modification of different functional groups for the development of new tryptanthrin derivatives with significant medicinal benefits as antitrypanosomal, 13 antifungal, 14,15 anti-phytopathogenic bacterial, 16 antibacterial, [17][18][19][20][21] anti-MRSA, 22 antiviral, [23][24][25][26] antiangiogenic, 27 anti-inflammatory, [28][29][30][31][32][33][34][35][36][37][38][39] anti-leishmanial, 40,41 antimalarial, 42 antiplasmodial, 43 antiparasitic, 44 antitubercular, [45][46][47] and anti-cancer [48][49][50][51][52][53][54]…”
