Inga represents a diverse genus of flowering plants that holds significant importance in both ecological and medicinal contexts. While many species are valued for their ability to fix nitrogen and enrich the soil, others are being closely studied for their complex biochemical properties. Recent scientific investigations have highlighted the plant's potential therapeutic activities, particularly regarding its antitumor effects. Researchers are working to isolate specific compounds that may inhibit the growth of malignant cells. Understanding these medicinal capabilities could eventually lead to new advancements in cancer treatment strategies.

Identification
Biological Activities
Inga species have demonstrated significant potential in pharmacological research due to their notable antitumor activity. Recent studies focusing on species like I. laurina and I. edulis have revealed that their extracts exhibit potent cytotoxic effects against various cancer cell lines, including HepG2, HT-29, and T98G. This biological effectiveness appears to be driven by a high concentration of bioactive polyphenols, such as aromatic acids, flavonoids, and tannins. Specifically, bioactive fractions from I. laurina seeds have shown high cytotoxicity against human colon cancer cells. Through proteomic analysis, researchers have also identified that these metabolites influence critical processes like apoptosis, DNA repair, and the elimination of reactive oxygen species.
