The preparation and characterisation of some derivatives of α-hydroxy-δ-lactones, in which the δ-carbon substituent on the lactone ring is trans to an adjacent isopropylidene protected diol, are described; the X-ray crystal structures of 3,4-O-isopropylidene-D-altrono-1,5-lactone and of 3,4:6,7-di-O-isopropylidene-D-glycero-Daltro-heptono-1,5-lactone are reported.

The synthesis and spectral characterisation of new glycoconjugated phthalonitrile connected with triazole linker via Cu(II)-mediated click reaction is reported. Treatment of azido derivative of 1-methoxy-2,3- O-isopropylidene-β-D-ribose with 4-O-propargyloxy-substituted phthalonitrile in presence copper(II) sulfate pentahydrate and sodium L-ascorbate in tert-butanol/water gave desired glycophthalonitrile with 84% yield. This precursor underwent mixed-cyclisation with the tert-butyl-substituted phthalonitrile, to afford the mono-glycosylated A3B-type platinum(II) phthalocyanine. Upon irradiation this compound could sensitise the formation of singlet oxygen in acetone, with 0.95 quantum yield by comparative method with use of 1,3-diphenylisobenzofuran (DPBF) as scavenger.

A novel series of carbohydrate-based naphthoquinones was synthesized and evaluated for cytotoxicity against different cancer cell lines. The compounds derived from 5-hydroxy-1,4-naphthoquinone (juglone) showed better cytotoxicity profiles against HCT-116, A-549 and MDA-MB 435 human cancer cells than the parent compound. The results suggest that the hydroxyl group on the aromatic ring increased the pro-oxidant activity of these new naphthoquinone derivatives. Furthermore, two derivatives were found to be more active against melanoma cells (MDA-MB435) than the clinically useful anticancer agent doxorubicin, and none of the compounds caused mouse erythrocyte lysis.
