Safety of 1-Iodo-2-methylbutane. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about Hydrophobic Pocket Occupation Design of Difluoro-Biphenyl-Diarylpyrimidines as Non-Nucleoside HIV-1 Reverse Transcriptase Inhibitors: from N-Alkylation to Methyl Hopping on the Pyrimidine Ring. 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.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Analysis of rotatory dispersions of configurationally related halides》. Authors are Levene, P. A.; Rothen, Alexandre; Marker, R. E..The article about the compound:1-Iodo-2-methylbutanecas:616-14-8,SMILESS:CCC(CI)C).Computed Properties of C5H11I. Through the article, more information about this compound (cas:616-14-8) is conveyed.

Rotatory dispersion curves of halides of the type HMeRC(CH2)nX (X = Cl, Br, I; R = alkyl group; n = 0, 1, 2 or 3) are analyzed in the visible and the ultraviolet regions. The 3 halogen atoms function similarly with respect to the character of this curve in compounds of identical structure. A periodicity in the sign of some of the partial contributions of the halogen atom occurs with increase in n. The course of the rotatory dispersion when n = 1 is anomalous. An attempt is made to apply results when n > 0 to the sign of rotation for compounds where n = 0. When X = COOH, CHO, CN, CHMe2, etc., no complete analogy exists between this group and the group where X is a halogen. [M]D25 maximum (homogeneous) is given for the 16 compounds where X = Br, n = 1, 2, 3, 4, and R = Et, Pr, Bu, pentyl, and for the compound HMeEtC(CH2)5Br. Absorption spectra are given for λ 2100-3300 for 5 iodides. Rotatory dispersion curves are given for the compounds HMeEtCCH2I, HMe(C6H13)CCH2I, HMeEtCCH2Br and HMeEtCCH2Cl. [M]D25 maximum, nD25, d425 (vacuum) and rotatory dispersions (numerical) are given for several other compounds in this series. Differences between the interpretation of the dispersions of the iodides given by the authors (C. A. 27, 951) and that given by Kuhn (C. A. 29, 7159.1) are due to substantial differences between their exptl. data.
