Most of the compounds in the chloroform fraction were identified as diterpenoids which may contribute to the apoptosis inducing activity of the fraction. (65)
• Antimicrobial Endophytic Fungi / Leaves: Plants have been reported to produce bioactive molecules. Study isolated an endophytic fungi from the leaves of Coleus amboinicus, identified as Athelia rolfsii. Two bioactive compounds were isolated and identified: methyl terpenoate as the major compound and methyl, 2,3 diene butanoate as the minor compound. The bioactive compound exhibited antimicrobial activities with IC50s of 0.86, 1.35, 1.33, 2.69, 1.9, and 0.24 µg/mL and MBCs of 4 µg/mL against S. aureus, E. coli, P. aeruginosa, B. subtilis, S. typhi NS 50, 40, 40, 40, 20, 20 µg/mL and MBCs of 40, 40, 40, 40, 20, 20 µg/mL against S. aureus, E. coli, P. aeruginosa, B. subtilis, S, typhi and S. mutans, respectively. (66)
• Anti-Inflammatory / Inhibitory Activity on Blocking the Activation of NLRP3 Inflammasome: Uncontrolled inflammation may produce massive inflammatory cytokines, with interleukin 1ß (IL-1ß) playing a key r9ole in tissue damage and serious disorders. The activation of NLRP3 inflammasome is one of the major mechanisms in maturation and release of IL-1ß. Extracts from P. amboinicus have been reported to have anti-inflammatory activity. PA-F4, an extract from P. amboinicus inhibited ATP-induced release of caspase-1, IL-1ß, and IL-18 from lipopolysaccharides (LPS)-primed cells. PA-F4 showed inhibitory activity on NLRP3 infllammasome activation. inhibited LPS-induced p65 NF-kB activation. Four constituents were identified in the PA-F4 viz., rosmarinic acid, cirsimaritin, salvigenin, and carvacrol, which inhibited LPS-induced IL-6 release. Study concludes the PA-F4 displayed inhibitory activity on activation of NLRP3 inflammasome. It inhibited LPS-priming step through blocking of p65 NF-kB activation, inhibited ATP-signaling pathways and the release reaction of caspase 1, IL-1ß and IL-18. (67)
• Effect on T47D Breast Cancer Cell Line: Study investigated the growth-inhibiting and apoptosis-mediating effect of P. amboinicus n-hexane extract on T47D cell lines. The extract inhibited the growth of T47D breast cancer cells in a dose and time dependent manner and could induce apoptosis. However, the combination with doxorubicin did not show synergistic effect. The results suggest the extract could be a potent agent for chemoprevention of breast cancer. (68)
• Anti-Inflammatory / Acute Toxicity Study / Leaves: Study evaluated the effect of leaves extract on induced arthritis in Wistar rats. Arthritis was induced by 2% uric acid and 1.5% oxonic acid intraperitoneally.

Bioaccumulation factor, translocation factor and metal extraction ratio of each plant were determined. Roots accumulated more Pb, followed by leaves and stems. Both plants were accumulators of Pb. P. amboinicus was most effective in removing lead from the soil even at high concentrations (600 ppm). (70)
