Abstract

Plant tissue culture is one of the main methods to supply the demand of anticancer drug derived from plants. Global demand for anticancer drugs from plants is very high, due to cancer is one of the main diseases that has the highest mortality rate in the world. This review article was written with the aim to summarize the latest developments plant tissue culture techniques to produce secondary metabolites with anticancer activity in the last 10 years. The method used to write this article is a literature review on the PubMed and Google Scholar database. The result showed that plant tissue culture techniques can increase the production of anticancer compounds derived from plants, especially through optimization of growth media, elicitation, and precursor feeding.

Abstract

A Self-Nanoemulsifying Drug Delivery System (SNEDDS) is a formulation approach used in the pharmaceutical and biotechnology industries to improve the solubility and bioavailability of poorly water-soluble drugs. Atorvastatin calcium has limited water solubility, which can affect its bioavailability when administered orally. Its solubility can be enhanced by various formulation techniques, such as the use of self-nanoemulsifying drug delivery systems (SNEDDS). The purpose of this study is to determine the formulation and characterization of SNEDDS and determine how it affects the bioavailability of atorvastatin calcium. The data were collected from published journals. The carrier components required in the formulation of atorvastatin calcium with SNEDDS formulation include oils (oleic acid, peceol, capyrol 90, and capmul CMC), surfactants (tween 80, tween 20, labrasol, cremophor RH 40) and co-surfactants (brij 30, propylene glycol, transcutol-P, PEG 400, transcutol HP). Characterization of atorvastatin calcium with SNEDDS formulation showed droplet size 21.6-162.2 nm; zeta potential -1.32 - 24.6±6.47 mV; and polydensity index 0.164 - 0.297. SNEDDS formulation increased the percentage of drug release and increased the bioavailability of atorvastatin calcium. Keywords: self-nanoemulsifying drug delivery system, SNEDDS, atorvastatin                      calcium, formulation, characteristics, dissolution, bioavailability

Abstract

Androgen receptor (AR) is the member of steroid hormone receptor involved in the progression of prostate cancer growth due to receptor over-activation. On the other hand, mangosteen (Garcinia mangostana L.) as a medicinal plant contains xanthone-derived compounds which were known to have cytotoxic activity towards any types of human cancer cells. This research aims to determine xanthone-derived isolates potency from mangosteen as AR antagonists. The study was carried out through molecular docking assay utilizing AutoDock 4.2.6 using androgen receptor obtained from PDB ID 2AM9, testosterone as native ligand, and bicalutamide, flutamide, and nilutamide as reference. The results indicated that three isolates (1,3,7-trihydroxy-2,8-di-(3-methylbut-2-enyl)xanthone, mangostinone, and trapezifolixanthone) have the highest potency to be AR antagonist seen from the lower bond-free energy value than all of reference ligand. The lowest bond-free energy was provided by mangostinone with a ΔG value of -10.05 kcal/mol. However, the highest difference of residual amino acids interaction with testosterone and similar interaction with bicalutamide was provided by 1,3,7-trihydroxy-2,8-di-(3-methylbut-2-enyl)xanthone, with five different amino acids with testosterone and nine similar amino acids with bicalutamide, respectively. Interestingly, 1,3,7-trihydroxy-2,8-di-(3-methylbut-2-enyl)xanthone has similar hydrogen bond with the key residue amino acids of AR (705-Asn and 711-Gln) which indicates probably partial agonist activity while mangostinone has the highest amount of hydrogen bond in the absence of hydrogen bond towards key residual amino acids of AR. The results concluded that three specific derived-xanthone compounds were predicted to have activity as AR antagonists.Keywords: Prostate cancer, Androgen receptor, Mangosteen, Xanthone, Molecular docking.
