Synthesis of 61-bis(1-adamantylcarbamoyl)-1,2-methano[60]fullerene and its antagonistic effect on haloperidol-induced catalepsy in mice
摘要:
The 61-bis(1-adamantylcarbamoyl)-1,2-methano[60]fullerene was synthesized from N,N'-di(1-adamantyl)malondiamide and C-60 in the presence of 1,8-diazabicyclo[5,4,0]-7-undecene. The intraperitoneal administration of this fullerene derivative (10 mg/kg) caused an antagonistic effect on hatoperidol-induced catalepsy in mice. (C) 2004 Elsevier Ltd. All rights reserved.
Design and Synthesis of Calcium and Magnesium Ionophores Based on Double-Armed Diazacrown Ether Compounds and Their Application to an Ion Sensing Component for an Ion-Selective Electrode
摘要:
The double-armed diazacrown ethers, which have a base diazacrown ether ring with two diamide-type side chains, were designed and synthesized on the basis of the proposed molecular model for the novel neutral Ca2+ and Mg2+ ionophores. The potentiometric ion-selective electrodes were prepared with over 20 kinds of systematically synthesized diazacrown ether derivatives. The relationship between the molecular structures of the ionophores and the ion selectivities was fully discussed. The electrodes based on the 21- and 18-membered diazacrown ether derivatives possessing a glycolic diamide and malonic diamide in their side chains (K23E1 and K22B5) exhibited excellent Ca2+ and Mg2+ selectivities, respectively. The ion-selectivity features of the novel Ca2+ and Mg2+ ionophores supply important structural information about the design of host molecules for alkaline earth metal cations.

A new preparative method for N-adamantylation of carboxylic acid amides, ureas and for C5-adamantylation of barbituric acid in trifluoroacetic acid (TFA) is proposed. Tertiary 1-adamantanols and 1-(1-adamantyl)alkanols were used as adamantylating agents. The reaction of 1-(1-adamantyl)alkanols with nitriles in TFA solution was employed for the first time for the preparation of N-[1-(1-adamantyl)alkyl]amides.
