A review of tobacco abuse and its epidemiological consequences
(Springer, 2021)
Aim The economic burden caused by death and disease in the world is credited mainly to tobacco use—currently linked to
approximately 8,000,000 deaths per year with approximately 80% of these faralities reported in low and ...
Synthesis, structural assignments and antiinfective activities of 3-O-benzyl-carvotacetone and 3-hydroxy-2-isopropyl-5-methyl-p-benzoquinone
(Taylor & Francis, 2021-11)
In an attempt to synthesize carvotacetone analogues, new 3-O-benzyl-carvotacetone (10) and previously reported 3-hydroxy-2-isopropyl-5-methyl-p-benzoquinone (11) were synthesized from piperitone (7). In this work, we ...
Synthesis of a pyrrolidine derivative of a carvotacetone and monoterpenes for anti-methicillin-resistant Staphylococcus aureus and anti-cryptococcal properties
(Taylor & Francis, 2022-05-03)
Monoterpene derivatives are of great biological relevance in the
pharmaceutical industry. In the present study, pyrrolidine deriva tive of a carvotacetone, 3-O-benzylcarvotacetone (1), and selected
monoterpenes ...
Isolation and detailed 1H and 13C NMR structural assignment for three trachylobanes from Psiadia punctulata (Asteraceae) grown in Africa
(Elsevier, 2022-04-01)
The first isolation of a trachylobane from an African specimen of Psiadia punctulata (Asteraceae) is presented in this paper. A complete 1H and 13C NMR spectral analysis of this compound and two other trachylobane diterpenes, ...
A new gnidiflavanone-flavonol dimer and other constituents from Gnidia apiculata
(Taylor & Francis, 2022)
A new 3,800-flavanone-flavonol dimer gnidiflavanone-flavonol (1)
and 10 known compounds (2–11), including four rare primula type flavones 2–5, were isolated from the roots of Gnidia apicu lata. Compounds 2–5 and 7 were ...
Utilization of fruit waste substrates in mushroom production and manipulation of chemical composition
(Elsevier, 2022-01)
The current study evaluated the effect of mushroom cultivation using fruit waste substrates on yield performance and antioxidant activities. The total phenolic content and the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical ...
Application of Crude Enzymatic Extract In Mushroom Processing To Recover High Value Products
(Research square, 2021-10-21)
In the present study, a fungal strain was isolated from mushroom waste dump-site and was described
based on the morphological and molecular characteristics. The crude enzymatic extract was prepared by
fermenting pineapple ...
Optimization of biodiesel synthesis from Jatropha curcas oil using kaolin derived zeolite Na–X as a catalyst
(Royal Society of Chemistry, 2022)
Biodiesel is an alternative renewable green fuel obtainable from the reaction of plant or animal oil with a low molecular weight alcohol in the presence of a catalyst. However, the cost of its production remains high due ...
Monoaminergic system involvement in the antidepressant-like and anxiolytic-like properties of novel β-dihydroagarofuran sesquiterpene alkaloid and triterpenes isolated from Gymnosporia heterophylla aerial parts in mice
(Pergamon, 2022)
Gymnosporia heterophylla (synonym Maytenus) is widely used in folk medicine for the treatment of various illness including neurological diseases. This study presents the antidepressant-like and anxiolytic-like effects of ...
Tuning the reactivity of ruthenium (II) terpyridyl complexes using auxiliary ligands: kinetic and mechanistic studies
(Springer International Publishing, 2022)
Substitution behavior of the labile aqua ligand in four mononuclear ruthenium(II) terpyridyl complexes with different auxiliary N (pyridine) (Ru1), N^N (2,2′-bipyridyl (Ru2), 2′-(2-pyridyl)quinoline (Ru3), 2,2′-biqunoline ...
