Tryptanthrin and its derivatives, representing a type of alkaloids with indoloquinazoline structures, were first obtained from blue plants and indigo, and then extracted from fungi, marine bacteria and a number of many other natural sources. Various strategies for their chemical synthesis have been reported while tryptanthrin biosynthesis has been less investigated. Tryptanthrin and its derivative products have a broad range of pharmacological and biological functions. In this review, we cover the sources, chemical synthesis and biosynthesis, modes of action and biological activities of tryptanthrin and its derivatives.

Tryptanthrin (tryp) is being studied as a lead compound with pharmacological activity that is found in nature. To date, synthetic and pharmacological studies on trypanthrin have focused on substitution patterns on the A and D rings, while structural modifications of the A ring system have yet to be explored synthetically. In this study, we synthesized a tryp derivative containing a five-membered heterocyclic ring (thiazole and thiophene) on ring A using solid-phase synthesis.

Tryptanthrin is a natural alkaloidal molecule [IUPAC name 6,12-dihydro-6,12-dioxoindolo-(2,1-b)-quinazoline], possessing an indoloquinazoline moiety. Since first being discovered in 1979, it and its analogs generated great interest in the fields of medicinal chemistry, life science, and materials science. Protocols for synthesizing tryptanthrins with the features of facile, eco-friendly, and mild reaction conditions remain an underdeveloped area.

Pigments, used as colouring agents for centuries, can be derived from nature or synthesized in labs. However, artificial dyes often pose health and environmental risks, leading to increased interest in natural pigments, particularly those from bacteria. This study investigates extracting and characterizing natural pigments from Micrococcus aloeverae (orange pigment) and Exiguobacterium aestuarii (yellow pigment).

The photophysical properties of a previously synthesized tryptanthrin incorporated spiropiperidine molecule (CTSP) is described. Studies revealed that the fluorescence of the compound gets significantly quenched by addition of picric acid (PA). The selectivity, anti-interference and quenching mechanistic studies are also described.
