合成了具有2,4,2,6,3,4和3,5位氯的非对映异构N,N'-二烷基双(二氯苯基)乙二胺和相应的咪唑烷。仅2,6-二氯取代的化合物的立体异构体对N-CH3(2e,3e),N-C2H5(2f,3f)和N-C3H7(2g,3g)表现出对雌二醇受体(Ka值范围从9.1 X 10(4)到9.1 X 10(6)),因为氮原子被邻位氯原子屏蔽;因此,与疏水性受体区域的结合相互作用是可能的。这些物质具有弱的子宫营养能力,并且对DMBA诱导的激素依赖性大鼠乳腺腺癌的生长没有明显影响。
Benzylamines: synthesis and evaluation of antimycobacterial properties
摘要:
The synthesis of benzylamines with various N-alkyl chains and substituents in the aromatic system as well as their evaluation on Mycobacterium tuberculosis H 37 Ra are described. The most active compounds in this test, N-methyl-3-chlorobenzylamine (19, MIC 10.2 micrograms/mL), N-methyl-3,5-dichlorobenzylamine (93, MIC 10.2 micrograms/mL), and N-butyl-3,5-difluorobenzylamine (103, MIC 6.4 micrograms/mL), also exhibited a marked inhibitory effect on Mycobacterium marinum and Mycobacterium lufu used for the determination of antileprotic properties. The combinations of 93 with aminosalicylic acid, streptomycin, or dapsone exert marked supra-additive effects on M. tuberculosis H 37 Ra.
The ortho-nitro effect was discovered in sulfa-Staudinger cycloadditions of ethoxycarbonylsulfene with linear imines. When an ortho-nitro group is present at the C-aryl substituents of linear imines, the sulfa-Staudinger cycloadditions deliver cis-β-sultams in considerable amounts, together with the predominant trans-β-sultams. In other cases, the above sulfa-Staudinger cycloadditions give rise to trans-β-sultams
