Sorption of methyl bromide on groundnuts》. Authors are Somade, H. M. B..The article about the compound:1-Iodo-2-methylbutanecas:616-14-8,SMILESS:CCC(CI)C).Application In Synthesis of 1-Iodo-2-methylbutane. Through the article, more information about this compound (cas:616-14-8) is conveyed.

Sorption of MeBr on groundnuts (I) was studied with both undecorticated I and I separated into husk, cotyledon, and germ. Successful treatment of I with MeBr depended on the moisture content of the nuts. Impairment of germination following MeBr treatment was observed when the moisture content exceeded 5%. Sorption of MeBr was found to increase more rapidly than the dosage, necessitating careful dosage control. At concentrations lower than that critical for a particular moisture content and period of fumigation, a slight stimulating action of MeBr on germination was observed.

Recommanded Product: 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 Two Distinct Thermal Stabilities of DNA and Enzymatic Activities of DNase I in a Multistep Assembly with Carbazole Ligands: Different Binding Characteristics for Duplex and Quadruplex DNA. Author is Inukai, Norie; Kawai, Tsuyoshi; Yuasa, Junpei.

A partially hydrophobic carbazole ligand ((Im+)2Cz: 2,2′-(9-ethyl-9 H-carbazole-3,6-diyl)bis(ethyne-2,1-diyl)bis(1,3-dimethyl-1 H-imidazol-3-ium)) adopts two different binding states (binding states I and II) in its interactions with calf-thymus (ct-) DNA. Two distinct binding states were identified by biphasic UV/Vis and CD spectral changes during the titration of DNA into the carbazole ligand. At low concentrations of ct-DNA, (Im+)2Cz binds to nearly every part of ct-DNA (binding state I). By contrast, an increased concentration of ct-DNA results in a switch in the DNA-binding state, so that the ligands are bound per five DNA base pairs. Similarly, a monocationic carbazole ligand (Im+Cz: 2-((6-bromo-9-ethyl-9 H-carbazol-3-yl)ethynyl)-1,3-dimethyl-1 H-imidazol-3-ium) also shows biphasic UV/Vis spectral changes during the titration of ct-DNA into Im+Cz, which suggests two different binding states of the Im+Cz ligand with ct-DNA. The stepwise equilibrium of the ligand-DNA-complex formation is capable of switching the thermal stability of ct-DNA, as well as the enzymic activity of DNase (DNase I). In binding state I, the (Im+)2Cz ligands interact with nearly every base pair in ct-DNA and stabilize the double-helix structure, which results in a larger increase in the melting temperature of the ct-DNA than that observed with binding state II. On the other hand, the (Im+)2Cz ligand significantly reduces the enzymic activity of DNase I in binding state I, although the enzymic activity is recovered once the binding state of the ligand-DNA complex is changed to binding state II. The (Im+)2Cz ligand was also employed as a binder for G-quadruplex DNA. In contrast to the stepwise complex formation between (Im+)2Cz and ct-DNA, (Im+)2Cz shows a monotonous UV/Vis spectral response during the titration of G-quadruplex DNA into (Im+)2Cz, which suggests a single binding state for (Im+)2Cz with G-quadruplex DNA.

Author is Ding, Li; Pannecouque, Christophe; De Clercq, Erik; Zhuang, Chunlin; Chen, Fen-Er.

Considering the nonideal metabolic stability of the difluoro-biphenyl-diarylpyrimidine lead compound I, a series of novel alkylated difluoro-biphenyl-diarylpyrimidines were designed and synthesized based on their structure. Introducing alkyl or substituted alkyl groups on the linker region to block the potential metabolic sensitive sites generated 22 derivatives Among them, compound II with an N-Me group displayed excellent anti-HIV-1 activity and selectivity. The Me group was hopped to the central pyrimidine to occupy the small linker region and maintain the water-mediated hydrogen bond observed in the binding of compound I with RT. The resulting compound III exhibited an improved anti-HIV-1 activity, much lower cytotoxicity, and nanomolar activity toward multiple mutants. In addition, III has a better stability in human liver microsomes than I. Moreover, no apparent in vivo acute toxicity was observed in III-treated female, especially pregnant mice. This series of alkylated compounds with highly potency and safety represent a promising lead template for future discovery.

Pyridinium poly(hydrogen fluoride) (30% pyridine-70% hydrogen fluoride): a convenient reagent for organic fluorination reactions. Author is Olah, George A.; Welch, John T.; Vankar, Yashwant D.; Nojima, Mosatomo; Kerekes, Istvan; Olah, Judith A..

Pyridinium polyhydrogen fluoride (30% pyridine-70% HF) reagent, a stabilized, less-volatile form of HF, is a convenient and effective fluorinating agent. Fluorination, halofluorination, nitrofluorination, and hydrofluorination of olefins were achieved using the reagent. The in situ diazotization and subsequent fluorinative dediazonization of α-amino acids, aminoarenes, and carbamates yielded α-fluorocarboxylic acids, aryl fluorides, and fluoroformates, resp. Geminal dihalides and α-halo ketones were treated with HgO in pyridinium polyhydrogen fluoride to form geminal difluorides and α-fluoro ketones. Solutions of alkali halides in pyridinium polyhydrogen fluoride were also effective halogenating agents for aminoarenes, via in situ diazotization and subsequent nucleophilic dediazonization by the corresponding halides, as well as for alcs., via SN2 displacement reactions. Diazo ketones and diazoalkanes also reacted smoothly with halide ions in pyridinium polyhydrogen fluoride solution to give the corresponding geminally halofluorinated compounds Proper precautions must be observed in using pyridinium polyhydrogen fluoride.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Aromatase inhibitors. Synthesis and evaluation of mammary tumor inhibiting activity of 3-alkylated 3-(4-aminophenyl)piperidine-2,6-diones, published in 1986, which mentions a compound: 616-14-8, mainly applied to aminophenylpiperidinedione preparation antitumor; piperidinedione aminophenyl preparation antitumor; aromatase placental inhibition aminophenylpiperidinedione; desmolase adrenal inhibition aminophenylpiperidinedione; estradiol inhibition aminophenylpiperidinedione, COA of Formula: C5H11I.

Piperidinediones I (R = H, Me, Et, Pr, CHMe2, CH2CHMe2, CHMeEt, pentyl, isopentyl, CH2CHMeEt, sec-pentyl, hexyl, heptyl) were prepared by alkylating PhCH2CN, addition reaction of PhCHRCN with CH2:CHCN, hydrolysis and ring closure of NCCRPhCH2CH2CN, nitration, and reduction of the nitro group. In vitro I showed a stronger inhibition of human placental aromatase than aminoglutethimide (II). The most active derivative, I (R = isopentyl), showed a 93-fold stronger inhibition than II. I, except I (R = CHMe2, CH2CHMe2, CHMeEt) exhibited equal or lower inhibition of bovine adrenal desmolase than II. Many I showed a stronger inhibition of the plasma estradiol concentration of pregnant mare serum gonadotropin-primed rats than II. They inhibited the testosterone-stimulated tumor growth of ovariectomized 9,10-dimethyl-1,2-benzanthracene tumor-bearing rats more strongly than II. Being stronger and more selective inhibitors of the estrogen biosynthesis than II, some of the newly developed derivatives of II might be better candidates for the treatment of hormone-dependent human breast cancer.
