  Alkylating derivatives of amino acids and peptides. Synthesis of N-maleoylamino acids, [1-(N-maleoylglycyl)cysteinyl]oxytocin, and [1-(N-maleoyl-11-aminoundecanoyl)cysteinyl]oxytocin. Effects on vasopressin-stimulated water loss from isolated toad bladder

  摘要：

  A method for the preparation of N-maleoylamino acids and esters is reported. These compounds were shown to inhibit both the oxytocin-induced smooth muscle contraction in the isolated rat uterus and the vasopressin-induced water loss from the isolated toad bladder. The inhibitory ability of the maleimides in the toad bladder assay was found to be related to their corresponding partition coefficients by the equation: log 1/C = -0.055 (log P) 2 + 0.227 log P + 3.96. N-Maleoylamino acids can be coupled to peptides to form alkylating reagents which react rapidly with sulfhydryl groups. The synthesis of [1-(N-maleoylglycyl)cysteinyl]oxytocin (3) and [1=(N-maleoyl-11-aminoundecanoyl)cysteinyl]oxytocin (4) as potential affinity labeling reagents is described. These oxytocin analogs were shown to readily react with sulfhydryl-containing compounds; however, neither 3 nor 4 was seen to inhibit in the rat uterus assay at concentrations up to 3 times 10(-5)M. When tested on the mucosal and serosal surfaces of the toad bladder, assay inhibition was seen only on the mucosal surface. These results are discussed with respect to the possible existence of sulfhydryl groups at neurohypophyseal receptors.

  Improved tack, green strength or non-black filler interaction capability are realized in a treated diene rubber. The method of treating diene rubberto achieve the improvements is shown, together with a composition in which maleamic acid or derivatives of maleamic acid are combined with sulfur or an organic sulfur compound capable of generating a thiyl radical.

  在经过处理的二烯烃橡胶中，粘性、生坯强度或非黑色填料相互作用能力都得到了改善。 图中展示了为实现上述改善而对二烯烃橡胶进行处理的方法，以及马来酰胺酸或马来酰胺酸衍生物与硫或能够生成硫基的有机硫化合物结合的组合物。
