- C-F bond substitution via aziridinium ion intermediates
-
Aliphatic 1,2-aminofluorides undergo extremely fast substitution reactions under the influence of lanthanum tris(hexamethyldisilazide). The substitution proceeds via an in situ generated aziridinium ion intermediate, which subsequently undergoes ring opening by addition of a nucleophile, yielding various β-substituted amines.

- Design and synthesis of imidazoline derivatives active on glucose homeostasis in a rat model of type ii diabetes. 2. Syntheses and biological activities of 1,4-dialkyl-, 1,4-dibenzyl, and 1-benzyl-4-alkyl-2-(4',5'- dihydro-1'H-imidazol-2'-yl)piperazines and isosteric analogues of imidazoline
-
Piperazine derivatives have been identified as new antidiabetic compounds. Structure-activity relationship studies in a series of 1-benzyl- 4-alkyl-2-(4',5'-dihydro-1'H-imidazol-2'-yl)piperazines resulted in the identification of 1-methyl-4-(2',4'-dichlorobenzyl)-2-(4',5'-dihydro-1'H- imidazol-2'-yl)piperazine, PMS 812 (S-21663), as a highly potent antidiabetic agent on a rat model of diabetes, mediated by an important increase of insulin secretion independently of α2 adrenoceptor blockage. These studies were extended to find additional compounds in these series with improved properties. In such a way, substitution of both piperazine N atoms was first optimized by using various alkyl, branched or not, and benzyl groups. Second, some modifications of the imidazoline ring and its replacement by isosteric heterocycles were carried out, proceeding from PMS 812, to evaluate their influence on the antidiabetic activity. The importance of the distance between the imidazoline ring and the piperazine skeleton was studied third. Finally, the influence of the N-benzyl moiety was also analyzed compared to a direct N-phenyl substitution. The pharmacological evaluation was performed in vivo using glucose tolerance tests on a rat model of type II diabetes. The most active compounds were 1,4-diisopropyl-2-(4',5'-dihydro-1'H-imidazol-2'- yl)piperazine (41a), PMS 847 (S-22068), and 1,4-diisobutyl-2-(4',5'-dihydro- 1'H-imidazol-2'-yl)piperazine (41b), PMS 889 (S-22575), which strongly improved glucose tolerance without any side event or hypoglycemic effect. More particularly, PMS 847 proved to be as potent after po (100 μmol/kg) as after ip administration and appears as a good candidate for clinical investigations.

- Synthesis of novel succinamide derivatives having the 5,11-dihydro-6h- pyrido[2,3-b][1,4]benzodiazepin-6-one skeleton as potent and selective M2 muscarinic receptor antagonists. I
-
A series of 5,11-dihydro-6H-pyrido[2,3-b][1,4]benzodiazepin-6-one derivatives containing the succinamide skeleton has been synthesized and evaluated for M1, M2 and M3 muscarinic receptor binding affinities (in vitro) and M2 and M3 muscarinic receptor antagonistic activities (in vivo). Some of them showed higher and more selective binding affinities for M2 muscarinic receptors than that of AF-DX 116. Among them, 11-[3-[N-[2-(N- benzyl-N-methylamino)ethyl]-N-ethylearbamoyl]propionyl]-5,11-dihydro-6H- pyrido[2,3-b][1,4]benzodiazepin-6-one (68) was found to be the most potent and selective M2 muscarinic receptor antagonist in vitro. This compound also strongly inhibited the oxotremorine-induced bradycardia after intravenous administration and showed 130-fold selectivity for M2 muscarinic receptors over M3 muscarinic receptors in vivo.

A new, technologically easily feasible process for the preparation of 2-(N-benzyl-N-methylamino)ethyl methyl 2,6-dimethyl-4(m-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate, comprising a partrial hydrolysis of dimethyl 2,6-dimethyl-4-(m-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate in an inert organic solvent at a temperature between room temperature and the reflux temperature of the reaction mixture with an aqueous solution of alkali hydroxide and the reaction of the obtained 3-methoxycarbonyl-2,6-dimethyl-4-(m-nitrophenyl)-1,4-dihydropyridine-5-carboxylic acid either with N-(2-hydroxyethyl)-N-benzyl-methylamine in the presence or absence of an organic solvent in the presence of N,N'-dicyclohexylcarbodiimide at a temperature of between 25° and 120° C. or with N-(2-haloethyl)-N-benzyl-methylamine in the presence of an inert organic solvent and of a proton acceptor at a temperature of between 25° and 140° C., to yield the title compound, which can be, if desired, converted to its hydrochloride salt. The hydrochloride salt is known under the generic name "nicardipine hydrochloride" and is used as a valuable therapeutic in the therapy of cerebral insufficiency.
