"Kanker payudara merupakan salah satu penyebab kematian pada perempuan di seluruh dunia. Pengobatan menggunakan bahan alam banyak dikembangkan karena toksisitasnya rendah. Daun sirsak (Annona muricata L.) terbukti memiliki potensi aktivitas antiproliferasi pada sel kanker payudara.
Penelitian ini bertujuan untuk memperoleh pengaruh enkapsulasi ekstrak etanol daun sirsak terhadap aktivitas antiproliferasi sel kanker payudara T47D. Liposom adalah mikropartikulat berbentuk sferis yang mampu menghantarkan obat antikanker.
Pada penelitian ini ekstrak etanol daun sirsak dienkapsulasi dalam liposom menggunakan metode hidrasi lapis tipis dan diekstrusi dengan membran polikarbonat 0,4 μm dan 0,1 μm masing-masing sebanyak 10 siklus. Selanjutnya, formula liposom yang memiliki enkapsulasi terbaik dilihat dari waktu pemisahan yang lebih lama dan dispersi partikel yang paling kecil kemudian dibandingkan aktivitas antiproliferasinya dengan ekstrak yang tidak dienkapsulasi menggunakan metode MTT.
Pada penelitian ini diperoleh bahwa liposom formula 1 memiliki dispersi partikel lebih kecil dan waktu pemisahan lebih lama dengan morfologi multi vesicular vesicle dan large unilamelar vesicle. Efisiensi penjerapan liposom formula 1 adalah 96,93%. IC50 ekstrak yang tidak dienkapsulasi adalah 64,53 μg/ml dan IC50 ekstrak yang dienkapsulasi liposom adalah 389,29 μg/ml.

Breast cancer is one the leading cause of cancer death in women worldwide. Treatment using natural materials has been developed because it has low toxicity. Soursop leaves (Annona muricata L.) proved to have the potential antiproliferative activity in breast cancer cells. Liposomes are spherical microparticulate which capable of delivering anticancer drugs.
This study aimed to obtain the effect of encapsulation soursop leaves ethanolic extract in liposome against antiproliferative activity in T47D breast cancer cell.
In this study, ethanolic extract of soursop leaf encapsulated in liposomes using thin layer hydration method and extruded with a polycarbonate membrane of 0,4 μm and 0,1 μm respectively as many as 10 cycles. Furthermore, liposome?s formula which shown the best encapsulation from longer separation time and smallest particle dispersion compared its antiproliferative activity with extracts not encapsulated using MTT method.
In this study showed that liposomes formula 1 has smaller particle dispersion and longer separation time whose multi vesicular vesicle and large unilamelar vesicle morphology. Entrapment efficiency of liposome formula 1 is 96,93%. IC50 value for not encapsulated extract was 64,53 μg/ml and IC50 value for extract encapsulated liposomes was 389,29 μg/ml."

"Aspergillus sp. dapat digunakan sebagai sumber senyawa bioaktif untuk menemukan obat-obatan baru antikanker. Penelitian bertujuan untuk mengetahui aktivitas sitotoksik ekstrak Aspergillus sp. Aspergillus sp. diisolasi dari Halymenia durvillaei yang diambil dari Pantai Binuangeun, Banten Selatan. Aspergillus sp. dikultivasi selama empat minggu pada suhu 27--29°C dalam medium Malt Extract (ME) pada kondisi statis. Senyawa metabolit sekunder dari medium kultur (broth) diekstraksi dengan etil asetat (2:1) sedangkan dari miselium diekstraksi dengan campuran metanol dan n-heksan (1:1). Uji sitotoksik dilakukan menggunakan sel kanker payudara T47D dengan metode uji 3-[4,5-dimetilthiazol-2yl]-2,5-difeniltetrazolium bromide (MTT). Hasil ekstraksi diperoleh ekstrak broth dan miselium sebesar 18,30 g dan 0,93 g. Uji sitotoksik terhadap sel kaker payudara T47D dengan metode MTT menghasilkan nilai IC50 untuk ekstrak broth dan miselium sebesar 153,266 ppm dan 208,305 ppm.

Many Aspergillus sp. were used as bioactive compound resources for obtaining a new anticancer. The aims of the research were to study cytotoxic activity of extract Aspergillus sp. againts Mammae Cancer Cell T47D. Aspergillus sp. was isolated from Halymenia durvillaei collected from Binuangeun Beach, South Banten. Aspergillus sp. was cultivated in medium ME (broth) for four weeks at room temperature at 27--29°C. Secondary metabolite produced from broth culture was extracted using ethyl acetate (2:1) and from the mycelium was sonicated followed by extraction using methanol and n-hexan (1:1). Cytotoxic assay of Mammae Cancer Cell T47D was carried out by 3-[4,5-dimetilthiazol-2yl]-2,5-difeniltetrazolium bromide (MTT) method. The yield of extract from broth and mycelium were 18,30 g and 0,93 g, respectively. Cytotoxic assay of Mamae Cancer Cell T47D resulted of IC50 153,266 ppm and 208,305 ppm for broth and mycelium extract."

"ABSTRAK
Kapang dari lingkungan laut (marine derived fungi) salahsatunya adalah Emericella
nidulans diketahui menghasilkan senyawa aktif emestrin. Penelitian ini bertujuan
untuk mengisolasi senyawa target selain senyawa emestrin dari fraksi teraktif yang
dihasilkan oleh ekstrak miselium kapang laut Emericella nidulans, mengetahui efek
sitotoksik senyawa target tersebut terhadap sel kanker payudara (T47D) dan sel
kanker leher rahim (HeLa). Selain itu, penelitian ini juga bertujuan untuk melakukan
produkasi senyawa target. Produksi senyawa target dari kapang laut Emericella
nidulans, dilakukan dengan tiga medium fermentasi yang berbeda yaitu Malt Ekstract
Broth (MEB), Soluble Starch Soytone (SWS) dan Minimum Fungi Medium (MFM).
Waktu yang digunakan untuk fermentasi produksi senyawa target adalah 1, 2, 3, 4
dan 5 minggu. Senyawa target selain emestrin berhasil diisolasi dari ekstrak
miselium Emericella nidulans. Senyawa target yang diisolasi memiliki perbedaan
dengan emestrin berdasarkan nilai rf pada KLT, serapan UV dan 1H-NMR. Senyawa
target memiliki aktitas sitotoksik yang kuat terhadap sel HeLa dan sel T47D dengan
IC50 berturut-turut sebesar 21,2 dan 20,9 μg/ml. Hasil produksi senyawa target
paling baik dihasilkan di medium Malt Ekstract Broth (MEB) pada minggu ke-3.

Abstract
Marine fungi Emericella nidulans has known as its emestrin active compound. In this
present study, we focused on extracting coumpounds beside emestrin as the most
targeted coumpound isolated from mycelium marine fungi Emericella nidulans in
cervix cancer cell (HeLa) and breast cancer cell (T47D). Productions from the
targeted compound were seeding in fermented media Malt Extract Broth (MEB),
Soluble Starch Soytone (SWS) and Minimum Fungi Medium (MFM). The timing
production of fermenting compound were 1,2,3, 4 and 5 weeks. The targeted
compound beside emestrin has been successfully isolated from Emericella nidulans
mycelium. The targeted compound was different with emestrin base on rf value on
TLC, UV and 1H-NMR spectrum. The targeted compound showed has a cytoxic
activity against HeLa and T47D cell with IC50 value of 21,5 μg/ml and 20,9 μg/ml
respectively. The highest yield of the targeted compound was found in MEB after 3
week of fermentation."
