<p>Asiatic pennyworth is a medicinal plant that contains triterpenoids, saponin, flavonoids, and tannins which possess antioxidants. Endophytic fungi from the plant could produce a similar compound; therefore, antioxidants could be made in the laboratory if the fungi are isolated. This study aimed to evaluate the potential of endophytic fungi isolated from Asiatic pennyworth to produce antioxidants. The study used 34 endophytic fungal isolates from Asiatic pennyworth accessions of Malaysia (17 isolates) and Bengkulu, Indonesia (17 isolates) collected by the Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development. The fungi were propagated in a potato dextrose broth medium, then mycelia mats and filtrates were separated and then freeze-dried. The antioxidant activities were first tested with 1,1-diphenyl-2- picrylhydrazyl (DPPH) using thin layer chromatography (TLC), then UV-Vis spectrophotometry λ517 nm with five variations of concentration. Results showed all 34 fungal isolates have antioxidant activities based on a yellowish-white color change after applying 0.002% DPPH solution of the TLC method and IC50 value of the UV-Vis spectrophotometer. The highest antioxidant activity was shown by <em>Aspergillus austroafricanus </em>MB 1 (IC50 = 12.08 ppm) from Bengkulu accession and <em>A. oryzae </em>MM 13 (IC50 = 10.29 ppm) from Malaysia accession. <em>A. austroafricanus </em>MB 1 produced more antioxidant compounds (seven) than <em>A. oryzae </em>MM 13 (six). The antioxidant compounds produced by both endophytic fungi included in the group of flavonoids, fatty acids, and carboxylic acids. The research implies that <em>A. austroafricanus </em>MB 1 and <em>A. oryzae </em>MM 13 could be further developed as sources of antioxidants.</p>

The genus Inula belongs to family Asteraceae and it is medicinally important because it possesses cytotoxic, anticancer, hepatoprotective, antibacterial and anti-inflammatory properties. The aim of this research was to explore antioxidant and anti-urease activities of fifteen Inula taxa in Turkey. Ethanol extracts of Inula taxa were obtained by Soxhlet extraction. Antioxidant activity was determined through total antioxidant activity, total phenolic content and copper reducing antioxidant capacity (CUPRAC) analyses. The highest total phenolic content and total antioxidant capacity were found in I. orientalis (158.54?0.002 ?g GAE/mL) and I. macrocephala (189.16?0.002 ?g AAE/mL). CUPRAC activity increases with the increasing concentration of the extracts and the standard. Moreover, all the tested plants exhibited better anti-urease activity than standard thiourea except for I. anatolica and I. thapsoides subsp. thapsoides. Results obtained from this study demonstrate that Inula species might be utilized as a probable natural source in the pharmaceutical and food industries but further and more specific studies are needed to determine active antioxidative and anti-urease compounds in the extracts.

A series of novel 2-oxo-1,2,3,4-tetrahydroquinolin-7-yl benzoate derivatives were synthesised and obtained in moderate yields (55-85%) by the reaction of parent 7-hydroxy-1,2,3,4-tetrahydroquinolin- 2-one (7-hydroxy-3,4-dihydroquinolin-2(1H)-one) with substituted benzoyl chlorides. The synthesised test compounds were characterised by spectral analysis. Partition coefficient was determined for all test compounds and was found to be in the range of 1.2-2.9. Further, the compounds were screened for their antibacterial and antioxidant activities. They were also randomly screened for their antidiabetic potential by non-enzymatic glycosylation of haemoglobin assay. However, the results revealed that test compounds did not possess antioxidant and antidiabetic potential comparable to that of their respective standards. The results also revealed that most of the compounds exhibited antibacterial action against four bacterial strains namely Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. Further, the test compound VIIl (at 500 µg mL-1), showed zone of inhibition comparable to that of the standard ciprofloxacin (at 500 µg mL-1).

Synthetic fatliquors are useful as a fatliquoring agent, flotation agent and emulsifying agent in a wide range of industrial applications such as leather, pharmacy and farm chemicals. These fatliquors remain recalcitrant to natural biota in existing treatment plants. In the present study, the isolated microaerophilic Serratia sp. HA1 strain CSMB3 is capable of utilizing structurally different fatliquors as the sole substrate for their growth under microaerobic conditions. Degradation of vegetable fatliquors was observed from 95 to 97% in terms of lipids, with the production of lipase at 72 h. Degradation of synthetic fatliquors was observed in terms of chemical oxygen demand from 85% to a minimum of 25%. It is in the order of sulfited/sulfated fatliquors &gt; sulfochlorinated fatliquors &gt; chlorinated fatliquors. A thin layer chromatography chromatogram confirmed the degradation of non polar fatliquor to polar compounds. Production of the red pigment prodigiosin in synthetic fatliquors enhanced the growth of the isolate. Fourier transform infrared spectroscopy (FTIR) confirmed the bioremediation of sulfochlorinated fatliquor into lipids and fatty acids and gas chromatography–mass spectrometry (GC-MS) results confirmed that alcohols and esters are the final end products. Thus the isolated strain CSMB3 may be used in the treatment of wastewaters containing vegetable and synthetic fatliquors.

Candida albicans and six other medically important Candida species were cultured on glucose–salts–biotin media containing tryptophan as the major nitrogen source. Candida albicans, C. tropicalis, and C. parapsilosis produced a pink pigment; C. krusei, C. pseudotropicalis, and C. gulliermondii formed brown pigments. Pigmentation of C. stellatoidea was variable, some strains produced brown pigments and others a pink pigment. Production of pink pigment was catalyzed by light. Cultures incubated in the dark produced only trace amounts of the pink pigment. Iron enhanced pigment production. Intense autofluorescence was observed for strains producing the brown pigment and weak autofluorescence for strains producing the pink pigment.

Employing a methodology that meets various requirements of "Green Chemistry", the substances quinazolinyl benzoate (P1) and N-4-imidazolphenylbenzamide (P2) were synthesized through benzoylation reactions by the classical Schotten-Baumann method, in an aqueous environment and room temperature. The products were purified by recrystallization and characterized by melting point, thin layer chromatography (TLC) and infrared spectroscopy. Qualitative antioxidant activities with the diphenylpicrylhydrazyl radical (DPPH) and toxic potential against Artemia salina Leach larvae were also investigated. Only P2 indicated significant antioxidant activity. According to the medium lethal concentration values (LC50), used for P1 and P2, the toxic potential revealed, respectively, to be moderate for P1 and weak for P2. Despite the low yield obtained for the synthesis of P1, the characterizations indicate success in the preparations, within a synthetic strategy of low cost, efficient and ecologically sustainable.
