Six compounds were synthesized from the lanostane-type tetracyclic triterpenoid of trametenolic acid B with the aim of obtaining more active compounds, which were characterized by NMR, IR, ESI-MS and elemental analysis. Their cytotoxic activities were evaluated against the breast cancer cell line MD-AMB-231. The compound 3b exhibited the best anti-proliferative effect than trametenolic acid B and other derivatives with the IC50 of 17.78 µM.

Study Results

The present research work is designed to prepare and evaluate piperine liposomes and piperine–chitosan-coated liposomes for oral delivery. Piperine (PPN) is a water-insoluble bioactive compound used for different diseases. The prepared formulations were evaluated for physicochemical study, mucoadhesive study, permeation study and in vitro cytotoxic study using the MCF7 breast cancer cell line. Piperine-loaded liposomes (PLF) were prepared by the thin-film evaporation method. The selected liposomes were coated with chitosan (PLFC) by electrostatic deposition to enhance the mucoadhesive property and in vitro therapeutic efficacy. Based on the findings of the study, the prepared PPN liposomes (PLF3) and chitosan coated PPN liposomes (PLF3C1) showed a nanometric size range of 165.7 ± 7.4 to 243.4 ± 7.5, a narrow polydispersity index (>0.3) and zeta potential (−7.1 to 29.8 mV). The average encapsulation efficiency was found to be between 60 and 80% for all prepared formulations. The drug release and permeation study profile showed biphasic release behavior and enhanced PPN permeation. The in vitro antioxidant study results showed a comparable antioxidant activity with pure PPN. The anticancer study depicted that the cell viability assay of tested PLF3C2 has significantly (p < 0.001)) reduced the IC50 when compared with pure PPN. The study revealed that oral chitosan-coated liposomes are a promising delivery system for the PPN and can increase the therapeutic efficacy against the breast cancer cell line.

Kanker payudara yang paling banyak ditemukan adalah subtipe luminal A dengan karakteristik Estrogen Reseptor+. Subjek penelitian akan diwakili oleh cell line MCF-7 dan Umbilical Cord Blood Mesenchymal Stem Cell (UCBMSC). Over expression Myc pada kanker payudara mengakibatkan sel kanker menjadi lebih invasif dan terjadi resistensi terhadap terapi hormonal. Tujuan penelitian ini adalah mengidentifikasi ekspresi gen Myc pada cell line MCF-7 sebelum dan sesudah pemberian sel punca. Penelitian ini menggunakan desain experimental secara in vitro. Sampel menggunakan MCF-7 dan sel punca yang dibagi menjadi 4 kelompok, yaitu K1 (kelompok kontrol MCF-7), K2 (kelompok kontrol sel punca), P1 (perlakuan subkultur MCF-7 dengan sel punca inkubasi 24 jam), dan P2 (inkubasi 48 jam). Kemudian, dilakukan isolasi RNA, sintesis cDNA, dan ekspresi Myc diperiksa menggunakan PCR dan elektroforesis. Analisa data yang digunakan adalan One Way ANOVA dan post-hoc LSD. Hasil analisis bivariat didapatkan p<0,05. Dari uji post-hoc LSD tidak ditemukan perbedaan yang bermakna antara K1 dengan P1, K1 dengan P2, dan K2 dengan P2. Namun, tetap ditemukan perbedaan yang bermakna antara K2 dengan P1 dan P1 dengan P2. Simpulan penelitian ini adalah tidak terdapat perbedaan bermakna ekspresi gen Myc pada subkultur antara MCF-7 breast cancer cell line dengan pemberian sel punca mesenkimal.
