In the course of our continuing search for anticancer compounds from Chisocheton species, three steroids, stigmast-5-en-3β-ol (1), stigmast-5-en-3β-ol-3-O-β-D-glucopyranoside (2) and stigmast-5,22-dien-3β-ol-3-O-β-D-glucopyranoside (3), were obtained from the stembark of Chisocheton celebicus. The structures of compound 1-3 were identified with spectroscopic data including IR, 1D-NMR, 2D-NMR and TOF-MS, as well as by comparing with those spectral data previously. Compounds 1-3, were evaluated for their cytotoxic effects against P-388 murine leukemia cells and displayed the cytotoxicity activity with IC50 values of 12.45 ± 0.050, 52.27 ± 0.031 and 62.52 ± 0.076 µg/mL, respectively.

Peptida antioksidan merupakan kelompok peptida yang berperan penting karena dapat menetralkan radikal bebas, sehingga dapat mencegah dan mengobati penyakit kronis. Salah satu senyawa peptida antioksidan alami yang telah ditemukan peneliti sebelumnya adalah senyawa tetrapeptida PAGY (Pro-Ala-Gly-Tyr) yang diisolasi dari gelatin kulit ikan amur sturgeon (Acipenser schrenckii) dan dilaporkan memiliki aktivitas antioksidannya dengan IC50 5.38 mg/mL dalam uji DPPH dan 0,008 mg/mL dalam uji ABTS berturut-turut. Kelompok kami telah berhasil mensintesis PAGY bersama dengan analognya yakni PSGY, PFFY, PAFY, dan PAIY dengan menggunakan metode sintesis peptida fase padat (SPPS). Pengujian aktivitas antioksidan pada senyawa hasil sintesis menunjukkan bahwa PSGY memiliki aktivitas antioksidan lebih baik dari PAGY. Pencarian analog tetrapeptida antioksidan yang lebih baik hingga saat ini masih terus dilakukan. Pada penelitian ini telah berhasil disintesis analog tetrapeptida lainnya PADY (Pro-Ala-Asp-Tyr) dengan metode sintesis peptida fase padat menggunakan strategi Fmoc/t-Bu pada resin 2-klorotritilklorida dilanjutkan dengan pengujian aktivitas antioksidannya. HATU/HOAT digunakan sebagai reagen pengkopling dalam sintesis PADY. Pemurnian krud PADY dilakukan menggunakan RP-HPLC preparatif sehingga diperoleh PADY murni seberat 14.7 mg (12.6%). Penentuan struktur peptida hasil sintesis dianalisis dengan menggunakan spektroskopi 1H-NMR dan TOF-MS. Pada pengujian aktivitas antioksidan dengan metode DPPH, PADY hasil sintesis memberikan nilai IC50 sebesar 1.850 mg/mL, yang mengindikasikan bahwa PADY menunjukkan aktivitas antioksidan yang lebih rendah daripada PAGY hasil sintesis peneliti sebelumnya. Kata kunci: Antioksidan, tetrapeptida, sintesis peptida fase padat. Antioxidant peptide is a class of peptides that play an important in neutralizing free radicals, therefore this compound can be used to prevent and treat chronic diseases. One of the natural antioxidant peptides reported by previous researcher is PAGY (Pro-Ala-Gly-Tyr), which is isolated from amur sturgeon fish (Acipenser schrenckii) gelatin that showed antioxidant activity with IC50 5.38 and 0.008 mg/mL using DPPH and ABTS assay, respectively. Our group has successfully synthesized PAGY, along with its analogues of PSGY, PFFY, PAFY, and PAIY using solid phase peptide synthesis method (SPPS). Antioxidant assay on synthesised compounds showed that PSGY has better antioxidant activity than PAGY. The search on the analogues of the antioxidant tetrapeptide was continued. From this study, a tetrapeptide analogue PADY (Pro-Ala-Asp-Tyr) has been successfully synthesised by solid phase peptide synthesis method with Fmoc/t-Bu strategy on 2-chlorotrityl chloride resin and tested for its antioxidant activity. HATU and HOAt reagents were used as the coupling reagent for the synthesis of PADY. The resulting PADY peptide solid was then purified using preparative RP-HPLC yielding PADY of 14.7 mg (12.6%). Characterisation of the synthesized compound was analysed by 1H-NMR and TOF-MS. On the antioxidant assay using DPPH method, PADY showed IC50 value of 1.850 mg/mLindicating a lower activity than the synthetic PAGY. Keywords: Antioxidant, tetrapeptide, solid phase peptide synthesis (SPPS).

Two steroid compounds, ergosterol peroxide (1) and stigmasterol (2) have been isolated from the stembark of Aglaia simplicifolia belong to Meliaceae family. The chemical structures of 1 and 2 were identified based on spectroscopic evidence including UV, IR, 1D NMR, 2D NMR as well as mass spectra and by comparison with those previously reported spectra data. Both compounds were evaluated for their cytotoxic effects against cervical cancer HeLa cells in vitro. Compounds 1 and 2 showed cytotoxicity activity against HeLa cervical cancer cells with IC50 values of 0.80 and 26.42 µM, respectively.

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.
