A short and versatile synthesis of alpha,beta-dibenzyl-gamma-butyrolactones has been developed starting from inexpensive materials by applying Stobbe condensation and following the novel reductive cyclisation with sodiumborohydride. Natural products Suchilactone (5a), Kaerophyllin (5b), savinin (5d) and anhydropodorhizol (5f) were prepared in racemic form. New thionolactones (6a?6e) were prepared by treating these lignans with Lawesson?s reagent. For all the prepared compounds the antioxidant, anti-inflammatory (5-lipoxygenase inhibition) and cytotoxic (Brine shrimp lethality test) activities were tested. The compounds 5a, 5b, 5c, 5d, 5e and 5f showed good 5-lipoxygenase inhibition activity. The thiono lignan 6d showed impressive cytotoxic activity.

(Chemical Equation Presented) Diastereoselective aldol reactions of chlorotitanium enolate derived from 20-hydroxypropiophenone are reported. The corresponding aldol products were prepared in moderate to excellent yields. In general, the expected syn diastereoisomers were obtained. Utilization of trans-cinnamaldehyde, 4-methoxybenzaldehyde, and 4-butoxybenzaldehyde in the aldol reaction afforded mainly unexpected anti aldol adducts. Three reasonable transition states for the reactions have been assigned to explain the diastereochemical outcome of the process depending on substitution pattern on aldehydes. This transition-state model using alkoxy at the 4-position of aromatic aldehydes considerably amplifies the synthetic utility of aldol reaction in diastereoselective synthesis.

Series of 5-substituted-3,4-diphenylfuran-2-ones were stereoselectively prepared. Their potential anti-proliferative effects on prostate cancer and some of their cyclooxygenases (COXs) inhibitory activities were evaluated. Structure-activity relationship (SAR) data, acquired by substituent modification at the para-position and ortho-position of the C-3 phenyl ring and 5-substituted modification of the central furanone, showed that 3-(2-chloro-phenyl)-4-(4-methanesulfonyl-phenyl)-5-(1-methoxy-ethyl) -5H-furan-2-one (13p) was the most potent compound and could effectively reduce the proliferation of prostate cancer cells (PC3 cell IC50 = 20 muM; PC3 PCDNA cell IC50 = 5 muM; PC3 SKP2 cell IC50 = 5 muM; DU145 cell IC50 = 25 muM). The cell cycle analysis for 13p in DU145 indicated that 13p may induce G1 phase arrest.

A new series of N-3,3-diphenylpropyl-N-(p-X-benzyl)-N?-phenylureas (5a-g) and thioureas (6a-g) were synthesized by the reaction of secondary amines and phenyl isocyanate or isothiocyanate. The cytotoxic effects of the urea and thiourea derivatives were evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide) assay against Ehrlich carcinoma and K562 human leukemia cells. Moreover, the activity of compounds in the inhibition of DNA topoisomerases I and II-alpha was tested.

Background: Cancers of the lymphatic cells (lymphomas) account for approximately 12% of malignant diseases worldwide. The nitrostyrene scaffold is identified as a lead target structure for the development of particularly effective compounds targeting Burkitt?s lymphoma (BL). Objectives: The aims of the curent study were to synthesise a panel of nitrostyrene compounds and to evaluate their activity in Burkitt?s lymphoma (BL). Methods: A panel of structurally varied compounds were designed and synthesised using Henry Knoevenagel condensation reactions. Single crystal X-Ray analysis confirmed the E configuration for six examples of these novel structures. A number of nitrostyrene-related compounds were also investigated including 1,3-bis(aryl)-2-nitropropenes together with heterocyclic scaffolds containing the nitrovinyl pharmacophore such as 3-nitro-2-phenyl-2H-chromenes. The antiproliferative activities of the compounds were evaluated using the BL cell lines EBV- MUTU-1 and EBV+ DG-75 (chemoresistant) to establish preliminary structure-activity relationships. Results: Lead compounds with optimized nitrostyrene scaffolds and 3-nitro-2-phenyl-2Hchromene structures were successfully established with typical IC50 values of 0.45 muM and 0.47 muM in MUTU-1 cells and 1.41 muM and 1.92 muM, respectively, in DG-75 cells. The mechanism of cell death was identified as apoptotic and the lead compound was found to elicit comparable apoptotic effects to Taxol in Burkitt?s lymphoma cell lines MUTU-1 and DG-75. Conclusion: This class of pharmaceutically active compounds with potential for the treatment of Burkitt?s lymphoma suggest a potential role for nitrostyrene based agents in chemotherapy.
