Sarcophytol A (1) and B (2) (see Chart 1) are cembrane-type diterpenes known to inhibit tumor promotion. Indicative of this inhibitory response, we currently report sarcophytol A (1) mediates dose-dependent diminution of 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced transformation of JB6 cells. Moreover, a structurally related furanocembrane diterpene, sarcophine (3), isolated in good yiel...

A total of seven fungi were identified from the surface of fully matured papaya fruits cv. ‘Sekaki’ collected form two different fields namely University Agriculture Park, UPM and MARDI, Selangor and a fruit exporter [Seng Chew Hup Kee (M) Sdn Bhd, Kajang, Selangor, Malaysia]. They were identified as Botryodiplodia theobromae, Colletotrichum capsici, C. gloeosporioides, Fusarium sp., Phomopsis ...

Monosulphides of O-phenyl-N-substituted phenylcarbamates were prepared by the reaction between Ophenyl-N-substituted phenylcarbamates and sulphur dichloride while the corresponding disulphides were prepared by the reaction between O-phenyl-Nsubstituted phenylcarbamates and sulphur monochloride. The synthesized compounds were characterized by elemental analysis, thin layer chromatography (TLC), ...

Transgenic ethylene-insensitive tobacco (Tetr) plants spontaneously develop symptoms of wilting and stem necrosis when grown in nonautoclaved soil. Fusarium oxysporum, F. solani, Thielaviopsis basicola, Rhizopus stolonifer, and two Pythium spp. were isolated from these diseased Tetr plants and demonstrated to be causal agents of the disease symptoms. Pathogenicity of the two Pythium isolates an...

Riddle, H. F. V. (1974). British Journal of Industrial Medicine, 31, 31-35. Prevalence of respiratory symptoms and sensitization by mould antigens among a group of maltworkers. The prevalence of allergic alveolitis, chronic respiratory symptoms, and sensitization by antigens from mould spores was investigated in 114 men employed at five maltings. Twentyfive carpet workers were used as a control...

Background: The production of waste pollutants has become a major problem for many food and oil industries. However, oil wastes can provide alternative substrates for industry, which could help to solve environmental pollution problems. Furthermore, oil wastes can be used as substrates to produce unsaturated fatty acids, which are important for health. Objectives: The production of fatty acids ...
