a facile one step synthesis of anilino alky1-n-substituted phthalimide i is reported. the following compounds belonging to this series were made: 1. (anilino-n-ethyl) phthalimide 8 2. (3,4, 5-trimethoxy anilino-n-ethyl) phthalimide 6 3. (3,4, 5-trimethoxy anilino-n-propyl) phthalimide 7 4. n-(ethyl phthalirnido-p-amino benzoyl) glutamic acid diethyl ester 10 5. n-(propyl phthalimido-p-amino ben...

Fruit wastes are one of the main sources of municipal waste. In order to explore the potential of fruit wastes as natural resources of bioactive compounds, the antioxidant potency and total phenolic contents (TPC) of lipophilic and hydrophilic components in wastes (peel and seed) of 50 fruits were systematically evaluated. The results showed that different fruit residues had diverse antioxidant...

The effect and responses to drought stress were analyzed in Quercus ilex L. seedlings using a nontargeted metabolomic approach, implementing the approaches of previous studies which other -omics platforms, transcriptomics, proteomics employed. This work aimed characterize Q. leaf metabolome, determining possible mechanisms molecular markers tolerance identifying putative bioactive compounds. Si...

BACKGROUND Medicinal plants are rich source of traditional herbal medicine around the globe. Most of the plant's therapeutic properties are due to the presence of secondary bioactive compounds. METHODS The present study analyzed the High Pressure Liquid Chromatography (HPLC) fractions of Puncia granatum (peel) extracts (aqueous, chloroform, ethanol and hexane) against multidrug resistant bact...

A series of cyclic analogues of bioactive thiosemicarbazide derivatives have been synthesized as potential antimycobacterial agents. The 4-amino-1,2,4-triazole-5-thione analogues (Ia-f) were prepared by heating a mixture of thiocarbohydrzide and appropriate carboxylic acids. Reaction of thiocarbohydrazide with γ-ketoesters in the presence of sodium methoxide furnished triazolopyridazine derivat...

Fruit quality is strongly affected by genotype and harvest date. In this study, parameters regarding fruit quality, bioactive compounds, antioxidant capacity of different strawberry cultivars at three harvesting dates were quantified to elucidate the influence date on quality. The results showed that was major contributor appearance color, TSS, TA, TSS/TA ratio strawberries, while mainly firmne...

An investigation was carried out to evaluate the influence of post-harvest application different ethylene inhibitors viz., 1-methylcylcopropene (1-MCP; 500, 1000 and 1500 ppb), methyl jasmonates (MeJA; 1, 2 3 mM) salicylic acid (SA; on health-promoting compounds such as total phenols, antioxidants, flavonoids, protein, free amino acids sugars in cold-stored ‘Kinnow’ mandarin fruit. The fruit we...

The authors report the synthesis of some bioactive organic compounds which could be pharmacological interest using Dioscorea praehensilis tyrosinase immobilized on calcium-alginate beads. enzymatic these involved pyruvic acid as a source carbonyl groups, ammonia and catechol. Catechol was used substrate parent compound that supplied aromatic ring carbons for reactions. structures novel synthesi...
