  5,6-Diaryl-2,3-dihydroimidazo[2,1-b]thiazoles: a new class of immunoregulatory antiinflammatory agents

  摘要：

  A series of substituted 5,6-diaryl-2,3-dihydroimidazo[2,1-b]thiazoles were synthesized and evaluated in the rat adjuvant-induced arthritis and mouse oxazolone-induced contact sensitivity assays to determine the potential of these compounds for use as immunoregulatory antiinflammatory agents. This class of compounds was derived by combining salient structural features of the antiinflammatory agent flumizole and the immunoregulatory drug levamisole. Unlike the latter two, a number of compounds in the target series were found to possess the desired combination of activities. Exploration of structure-activity relationships in the adjuvant-induced arthritic rat assay revealed that optimal potency was exhibited by symmetrically substituted 5,6-diaryl compounds having one of the following alkyl heteroatom or halogen functions at the para position: methoxy, ethoxy, methylthio, N-ethyl-N-methylamino, fluoro, or chloro. Scrambling of these two substituent classes to yield the asymmetrically substituted 5,6-diaryl compounds resulted in potent activity only with the 5-alkyl heteroatom, 6-halo-substituted regioisomers. However in the oxazolone-induced contact sensitivity assay, no consistent relationship of variation in activity with structural change was apparent. The initial target compound 5,6-bis(4-methoxyphenyl)-2,3-dihydroimidazo[2,1-b]thiazole (1) was compared with its progenitors in additional models of inflammation and immunoregulation.

  α-叠氮基苯乙酮中α裂解与能量转移之间的竞争

  摘要：

  分子建模表明，叠氮化物1b中三重态酮的第一激发态（T 1K）具有（π，π*）构型，其能量比其基态和第二激发态（T 2K）高66 kcal / mol。能量高10 kcal / mol，并具有（n，π*）构型。相比之下，叠氮化物1a的T 1K和T 2K分别以（n，π*）和（π，π*）构型在高于基态74和77 kcal / mol时简并。由于形成了T 1K，叠氮化物1b在甲醇中的激光快速光解（308 nm）产生瞬态吸收（λmax = 450 nm），其衰减速率为2.1×105 s -1形成三重态亚烷基二烯2b（λmax = 320 nm）。测得的腈2b的寿命为16毫秒。相反，叠氮化物1a的激光快速光解（308 nm）由于形成了亚硝基2a（λmax = 320 nm）和苯甲酰基3a（λmax = 370 nm）而产生了瞬态吸收光谱。在甲醇中，3a的衰减为2×10 5 s -1，而亚硝基2a的衰减率为〜91

  4,5-Diphenyl-2-oxazolenonanoic acid (2) and 2-[3-[2-(4,5-diphenyl-2-oxazolyl)ethyl]phenoxy]acetic acid (3) were previously identified as nonprostanoid prostacyclin (PGI2) mimetics that inhibit ADP-induced aggregation of human platelets in vitro. The effects on biological activity of substitution and structural modification of the 4- and 5-phenyl rings of 3 was examined. Potency showed a marked sensitivity

  methanol yields a transient absorption (λmax = 450 nm) due to formation of T1K, which decays with a rate of 2.1 × 105 s-1 to form triplet alkylnitrene 2b (λmax = 320 nm). The lifetime of nitrene 2b was measured to be 16 ms. In contrast, laser flash photolysis (308 nm) of azide 1a produced transient absorption spectra due to formation of nitrene 2a (λmax = 320 nm) and benzoyl radical 3a (λmax = 370 nm). The
