The synthesis of new organophosphorus and organosilicon compounds possessing insect juvenile hormone activity is described. The structure of the prepared compounds is confirmed by NMR spectra.
Here, we report the systematic synthesis and characterization of simple phenols bearing a trialkyl(aryl)silyl or trialkyl(aryl)germyl functional group as a hydrophobic substituent. These silicon and germanium analogues exhibited higher hydrophobicity than the corresponding carbon analogues, with a difference in log P value of approximately 0.6, independent of the alkyl(aryl) species. Trimethylsilylphenol and trimethylgermylphenol exhibited smaller pK(a) values than the corresponding carbon analogue or unsubstituted phenol, indicating that trialkylsilyl and trialkylgermyl functional groups have a negative substituent constant (sigma). The trialkylsilyl- and trialkylgermylphenols exhibited more potent estrogenic activity as compared with the carbon analogues. The substituent parameters and structure-activity relationship reported here may be helpful for drug discovery utilizing the heavier group 14 elements.

Sila‐Rythmol (11b), ein Sila‐Analogon des Antiarrhythmicums Rythmol (11a), wurde erstmalig dargestellt. 11b sowie die Vorstufen und Nebenprodukte 4, 5, 6, 7, 9b und 10b wurden in ihren physikalischen und chemischen Eigenschaften charakterisiert und in ihrer Struktur sichergestellt. Die pharmakologischen und toxikologischen Eigenschaften der Analoga 11a und 11b wurden vergleichend untersucht.
Sila-Rythmol (11b) 是抗心律失常 Rythmol (11a) 的 Sila 类似物,首次出现。对11b以及前体和副产物4、5、6、7、9b和10b的物理和化学性质进行了表征,并验证了它们的结构。比较地检查了类似物11a和11b的药理学和毒理学特性。
