In addition to the w-5 olefinic acids found in other Grevillea species, about 10% ?f the acyl groups of G. decOI'a seed oil contain a hydroxy group and an w-5 double bond. Th: chamlengths of these acids are from C22 to C30 , with the largest concentration at the C26 and C28 chamle.ngths. ~le hydroxy group is located on odd carbons from carbon-5 through carbon-l3. These a~lds prevIously .were ~n...
Cortisol, 11-deoxycorticosterone, progesterone, 17 alpha-hydroxy-progesterone, 17 alpha-hydroxy-20 beta-dihydroprogesterone, or a combination of the last 2 steroids, were injected into different groups of immature female Epinephelus. None of the steroids tested had significant effects on serum electrolyte level, and hepatosomatic and gonadosomatic indices. Serum glucose concentration was elevat...
Dichloromethane root extract of Rennellia elliptica Korth. showed strong inhibition of Plasmodium falciparum growth in vitro with an IC₅₀ value of 4.04 µg/mL. A phytochemical study of the dichloromethane root extract has led to the isolation and characterization of a new anthraquinone, 1,2-dimethoxy-6-methyl-9,10-anthraquinone (1), and ten known anthraquinones: 1-hydroxy-2-methoxy-6-methyl-9,10...
Investigation of the constituents of the fruits of Morus alba LINNE (Moraceae) afforded five new nortropane alkaloids (1-5) along with nor-psi-tropine (6) and six new amino acids, morusimic acids A-F (7-12). The structures of the new compounds were determined to be 2alpha,3beta-dihydroxynortropane (1), 2beta,3beta-dihydroxynortropane (2), 2alpha,3beta,6exo-trihydroxynortropane (3), 2alpha,3beta...
Three new lignans, sambucunol A (8) ((+)-erythro-1-(4-hydroxy-3-methoxyphenyl)-2-[4-(4-hydroxy-3-methoxycinnamoyloxypropanyl)-2-hydroxyphenoxy]-1, 3-propanediol), sambucunol B (9) ((+)-threo-1-(4-hydroxyl-3-methoxyphenyl)-2-[4-(4-hydroxy-3-methoxy-cinnamoyloxy propanyl)-2-hydroxyphenoxy]-1, 3-propanediol) and buddlenol G (10) (2-{4-[2, 3-dihydro-3-hydroxymethyl-7-hydroxy-5-(4-hydroxy-3-methoxyc...
The carcinogenicities for rats and mice of N-methyl-4-aminoazobenzene (MAB) and its hepatic microsomal metabolite N-hydroxy-N-methyl-4-aminoazobenzene (N-hydroxy-MAB) were compared under several conditions. N-Ethyl-4-aminoazobenzene, 4-aminoazobenzene, and their N-hydroxy derivatives were also included in some of the assays. About 25% of the rats given MAB or N-hydroxy-MAB (3 to 5 mmol/kg body ...
A novel binary compounds as 3-(1,3-diphenyl-1H-pyrazol-4-yl)-2-phenyl-2H-benzo[f]indazole-4,9-dione (10) and fused 2-hydroxy-3-(4-hydroxy-7-methoxy-2-oxo-1,2-dihydroquinolin-3-yl)naphthalene-1,4-dione (7) naphtho[2,3-b]furan-3,4,9(2H)-trione (6) based on lawsone ‘that plays important precursor’ was synthesized by reaction with 1,3-diphenyl-1H-pyrazole-4-carbaldehyde halo-compounds, such 2-chlor...
This study highlights the potential of ?-hydroxy amines as building blocks for aza-Michael CANs.
five new 1-hydroxy-2-(1-alkyloxymethyl)-9,10-anthraquinones (9a-e) have been prepared. selective nitration of 2-methyl-9,10-anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-2-methyl-9,10-anthraquinone in good yield as the key intermediate. reaction with dimethylsulphate/k2co3 and subsequent monobromination with nbs...
Case presentation: Male patient, 6 months old, admitted due to seizure associated with severe refractory hypoglycemia. Patient had been experiencing unusual sleepiness for 8 days, and vomiting after feedings. Brain CT showed prominence of the bilateral frontotemporal extra-axial space Sylvian fissures, EEG revealed a slow diffuse moderate disturbance background activity MRI extensive areas diff...
