The Chisocheton genus belongs to the Meliaceae family which produces various structures and activities of compounds, such as antimalarial, antimicrobial, antitumor, anti-inflammatory, and cytotoxic. This plant has 53 species that are spread in tropical and sub-tropical forests, including Indonesia. Chisocheton plants have been known as plants that produce limonoids, namely triterpenoid compounds that have been modified to lose four terminal carbons (tetranortriterpenoids). One of the species whose phytochemical reports are still few and interesting for research on limonoid content is Chisocheton macrophyllus. Chisocheton macrophyllus is a tall plant that grows in the rainforest in the northern part of the island of Sulawesi, Indonesia, has the regional name ma aa, gula, pasak lingga, gending, ta suea, bekak, or pithraj tree. This paper will describe a limonoid compound, namely nimonol which has been isolated from Chisocheton macrophyllus. Nimonol is known to have the molecular formula C28H36O5 from a group of havanensin. The structure was determined by spectroscopic methods UV, IR, 1D-NMR (1H-NMR, 13C-NMR, and DEPT), 2D-NMR (1H-1H COSY, HMQC, and HMBC), and mass spectroscopy.

Bacicyclin is a cyclic hexapeptide with antibacterial activity against Enterococcus faecalis and Staphylococcus aureus with minimum inhibition concentration (MIC) values of 8 and 12 µM, respectively. Studies on a reversed sequence of bacicyclin were conducted to investigate how the reversed peptide sequence affects its biological properties. A reversed-bacicylin, cyclo-(Gly-Leu-Val-Ile-Ala-Phe), was successfully synthesized by constructing the linear precursor on 2-chlorotrityl chloride resin using a Fmoc-based strategy. The HATU/HOAt reagent was applied in all peptidic bond formations, and the desired linear hexapeptide (82% yield) was cleaved off the resin using a mixture of trifluoroacetic acid:dichloromethane (2:8). The linear peptide was cyclized using 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium-3-oxidehexa-fluorophosphate (HATU) as a coupling agent and diisopropylethylamine (DIPEA) as the base in a very dilute solution (0.001 M) in dichloromethane, then purified by octadecyl silica gel (ODS) column chromatography to obtain the reversed-bacicyclin (43.7% yield). The purity of the cyclic product was analyzed using analytical RP-HPLC (tR = 20.01 min), and characterized by HR-TOF-MS, 1H-NMR, and 13C-NMR. The biological activity of the reversed-bacicyclin is much lower compared to bacicyclin, indicating that the amino acid sequence of the cyclopeptide dictates the antibacterial activity. This finding gives additional information on the relationship between peptide sequence and biological properties.

Indonesia is a tropical country with biodiversity and a source of natural compounds such as terpenoids, phenolic, flavonoids, and alkaloid groups. The steroid is one of the large groups of terpenoid compounds with various structures and bioactivities. The steroid was also commonly found in the Meliaceae family. One species of this family is Lansium domesticum Corr. which has been studied to have various activities from isolated compounds (limonoids, sesquiterpenoids, onoceranoids, cycloartanoids, and steroids) as well as from their extracts such as antidiarrheal, antimalarial, antimicrobial, antiinsecticide, antifeedant and were used as traditional medicine such as eye drops and scorpion stings. The n-hexane fraction from the bark of L. domesticum Cor. cv. Kokosan produced steroid compounds whose structure is determined by IR, 1H-NMR, 13C-NMR, and DEPT spectroscopy methods and compared with the literature. It was concluded that the steroid isolated was (22E)-stigmasta-5,22-dien-3ol and was first isolated from this genus. This compound was inactive against MCF-7 breast cancer cells with an IC50 value of 832.14 µM.
