Reference of 1-Iodo-2-methylbutane. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about Long-chain syn-1-phenylalkane-1,3-diyl diacetates, related phenylalkane derivatives, and sec-alcohols, all possessing dominantly iso-branched chain termini, and 2/3-methyl-branched fatty acids from Primula veris L. (Primulaceae) wax. Author is Radulovic, Niko S.; Zivkovic Stosic, Milena Z..

Herein, the results of the first study of non-flavonoid constituents of aboveground surface-wax washings of Primula veris L. (Primulaceae) are presented. Chromatog. of the washings yielded a minor fraction composed of n-, iso-, and anteiso-series of long-chained syn-1-phenylalkane-1,3-diyl diacetates, 3-oxo-1-phenylalkan-1-yl acetates, 1-phenylalkane-1,3-diones, 1-hydroxy-1-phenylalkan-3-ones, sec-alcs. (2- to 10-alkanols), and n-, iso-, anteiso-, 2-methylalkanoic and 3-methylalkanoic acids; 118 of these constituents represent up to now unreported natural compounds The structural/stereochem. elucidation was accomplished by the synthesis of authentic standards, derivatization reactions, the use of gas chromatog. retention data and detailed 1D and 2D-NMR analyses of the obtained complex chromatog. fraction. Primula veris produces unusually high amounts of branched long-chained metabolites (>60%) except for the fatty acids where the percentage of branched isomers is comparable to the ones with n-chains. Noteworthy is the fact that long-chained α- and β-Me substituted fatty acids were detected herein for the first time in the kingdom Plantae.

We report characteristics of the cerebrospinal fluid (CSF) pleocytosis (616+/-148 cells/microliter) that occurred in guinea-pigs with definite clinical experimental allergic encephalomyelitis developing 12 to 16 days after sensitization with homologous myelin basic protein. This pleocytosis was not present in the cerebrospinal fluid of a group of animals studied when still healthy, 9 or 10 days after similar sensitization. Eighty-nine per cent of cells in the CSF pleocytosis were small lymphocytes, 8% were larger lymphocytes and the remainder mostly monocytes. Of the lymphocytes, most were E-rosetting or null cells. B-cell markers were uncommon. The cellular patterns in this CSF pleocytosis appear to be similar to those seen in some delayed hypersensitivity responses.

Simple, rapid and reproducible stability-indicating methods were established for quant. determination of azathioprine using a, phenomenex 250 mm × 4.9 mm C18, 5 μm, inertsil and UV detection at 240 nm. The isocratic elution was used to quantify the analyte and the mobile phase was acetate buffer: acetonitrile: methanol (30: 35: 35) was pumped at 1.0 mL/min. The method was linear between 10-300 μg/mL, statistically validated for its linearity, precision and accuracy. In this study, degradation behavior of azathioprine was studied by subjecting the drug to various ICH stress conditions. The intra and inter day variation was found to be less than 1% showing high precision of the assay method. It was found that the excipients in the com. tablet did not interfere with the method. Developed method can routinely use for the estimation of azathioprine related compounds from the dosage form and also for stability sample.
