Method: Recently, plant hormones have been considered to reduce fungal severity. Five different plant hormones namely 2, 4-D (2,4Dichlorophenoxyacetic acid); BAP (6Benzylaminopurine); Dicamba (3,6Dichloro-2-methoxybenzoic acid, 3,6-Dichloro-o-anisic acid); IAA (Indole-2-acetic acid) and SA (Salicylic acid) were selected to examine their antifungal activity against the growth of two species of d...

this article examines al-ṭūsī’s and maghribī’s recensions of theodosius’ sphaerica by comparing their features and differences. al-ṭūsī adheresto the original text of sphaerica, however, by adding some postulates and three lemmas, he enriches the mathematical structure of the treatise. al-ṭūsī’s composition style reveals that he intended to prepare a pedagogical textbook, his statements are con...

Using appropriate precursors, the two unnatural alkaloids 4(5)-[N-isocaproylaminomethyl]imidazole and 3-[2-N-isovalerylaminoethyl]pyrazole were produced by Dolichothele sphaerica. The former compound represents an unnatural alkaloid formed by the simultaneous introduction of two unnatural precursors, namely isocaproic acid and 4(5)-aminomethylimidazole. The latter compound represents an aberran...

Five new 2(5H)-furanone-type derivatives, pestalafuranones F-J (compounds 3-7), together with two known compounds, pestalafuranones A (1) and B (2), were isolated from the ethyl acetate extract from the fermentation broth of the endophytic fungus Nigrospora sp. BM-2 in a hypersaline medium. The structures of these metabolites were elucidated by EIMS, HREIMS and NMR spectroscopic data. Compounds...

Cr(III), Co(II), Ni(II), Cu(II) and Zn(II) salts of 2-(4-nitrophenylaminocarbonyl)benzoic acid were characterized by physical, analytical and spectroscopic studies and checked for their in-vitro antimicrobial activity against three bacterial strains, Mycobacterium smegmatis (Gram +ve), Escherichia coli (Gram -ve), Pseudomonas aeuroginosa (Gram -ve) and three fungal strains, Nigrospora oryzae, A...
