本文首先指出,从对称类型(点群)来判断分子的极性是极其麻烦的,如根据特征对称要素则能快速而准确地做出判断。这对于有关的教学工作有其实际意义。其次指出,非极性分子的特征对称要素除一般所知的对称中心外,还有高次反轴4,6,8,10等也是特征对称要素。除此之外,并发现如分子本身井无特征对称要素,但其各基矩有对称中心及高次反轴则亦为非极性分子,如C(NO_2)_4,Al(BH_4)_3等就是如此。

Two polyfunctional crystalline proteinase inhibitors A and B were obtained from Sagittaria sagittrifalia L., each with two identical active centers. The relatively high activity and polyf unctionality of this inhibitor are quite unusual among similar plant proteinase inhibitors.Both A and B could inhibit trypsin as well as chymotrypsin and kallikrein from swine subaxillary gland. The weight ratio of A or B to trypsin inhibited was determined using the following trypsin substrates: casein, benzoyl arginine ethyl ester and benzoyl arginine α-naphthyl amide. With different substrates the ratios obtained were rather close, the mean values being 2.70 and 2.86 for inhibitors A and B respectively. The dissociation constants were found to be in the range of 10~(-9) to 10~(10). The weight ratios of A and B to chymotrypsin required for inhibition to the extent of 50% were also determined using casein, benzoyl tyrosine ethyl ester or nicotinyl tyrosine hydrazine as substrate. B showed a stronger affinity for trypsin than A, while A was apparently a more efficient inhibitor for chymotrypsin and kallikrein than B.The molecular weights of inhibitors A and B were determined by means of gel filtration on Sephadex and electrophoresis on polyacrylamide gel and both were found to be about 17,000. From the activities of inhibitors A and B towards trypsin, assuming one to one combination, it was estimated that the effective molecular weights of both A and B were about 8500, so it was inferred that, like the mung bean trypsin inhibitors, A and B also contain two active centers with the same biological function.The amino acid compositions of inhibitors A and B were similar except for slight differences in the content of basic amino acids. Both of them were found to contain two disulphide bonds and to be rich in non-polar acids (>60%). The minimum molecular weights as estimated from the amino acid compositions were about 16,500. For both inhibitors A and B the N-terminal amino acid was aspartic acid, as determined by the FDNB and DNS-Gl methods and further confirmed by enzymic hydrolysis with aminopeptidase M.

由于蛋白酶抑制剂在生理、生化、病理、药理上都占有很重要的地位,特别是具有多功能的蛋白酶抑制剂被广泛应用于临床,近年来愈来愈受到各方面的重视。本文报道了从慈菇中提取两种结晶的多功能蛋白酶抑制剂,它们都具有两个活力相等的活性中心,这与其他已知的同类型植物蛋白酶抑制剂不同,有它的特殊性。(1)慈菇蛋白酶抑制剂A、B,除能抑制胰蛋白酶外,还能抑制胰凝乳蛋白酶及猪颌下腺的舒缓激肽释放酶。用酰胺、酯及蛋白等不同底物分别求出抑制剂A、B对胰蛋白酶的当量抑制比值及对胰凝乳蛋白酶的半抑制比值。两者对胰蛋白酶的抑制常数在10~(-9)~10~(-10)的范围内,抑制剂B对胰蛋白酶较之A有更大的结合力,但抑制剂A对胰凝乳蛋白酶及舒缓激肽释放酶较之B却有更明显的抑制活力。(2)用葡聚糖凝胶过滤及聚丙烯酰胺凝胶电泳分别测定抑制剂A、B的分子量均在17000左右。从抑制剂A、B对胰蛋白酶的当量抑制比值求得分子量为8500。这说明每一抑制剂分子中具有两个活力相等的活性中心。(3)测定了抑制剂A、B的氨基酸组成,二者除碱性氨基酸及天冬氨酸含量略有差异外其余皆相同,各含有两对二硫键,非极性氨基酸含量较高约占60%左右。由氨基酸组成求得最小分子...
