About the Cover

In our ongoing search for anticancer compounds from natural products we chromatographed cytotoxic active extracts from medicinal plants growing in Omanin order to isolate their active ingredients. We hereby report isolation of a cytotoxic pimarane diterpenoid, 3-hydroxy-ent-pimara8(14),15-dien-19-oic acid (1) from hexane extract of Juniperus servaschanica collected from Oman. The anticancer property was evaluated against ovarian (MCAS) and breast (MDA MB231) cancer cell lines by Alamar-blue assay. Compound 1 was active against both ovarian and breast cancer cells (IC50 = 24.16 and 16.13 µg/ml, respectively). Additionally, the molecule showed little damaging effect against non-cancerous cells, fibroblast at its IC50 dosage. Further investigation on this metabolite and its derivatives might lead to discovery of new chemical entities for control of cancer.

A novel validated method for estimation of Carbachol in ophthalmic preparations by spectrophotometer

Abdul Munan, Akhtar Jamal Khan, Mahwash Khan, Abdul Haleem, Muhammad Ishaq Nazeer

A simple and selective novel spectrophotometric method has been proposed for determination of Carbachol in pure and pharmaceutical ophthalmic preparations. The method is developed on formation of ion-pair complex between Bromophenol blue (BPB) and Carbachol (Carb), which is blue in color

Effects of Novel Silver (I) NHeterocyclic Carbene Complexes on Mycotoxin Producing Fungi and Biofilm Forming Microorganisms

Esin Poyrazoğlu Çoban, Engin Ertuğrul, Rukiye Fırıncı, Halil Bıyık, Muhammet Emin Günay

Ag (I) complexes were prepared for a series of NHC substituents. Firstly, NHC precursors (1-9) were synthesized. In the second step, Ag (I) -NHC complexes (10-15) were synthesized. Structure of silver (I) N-heterocyclic carbene complexes was analysed using 1H- and 13C-NMR spectroscopy
