Organocatalytic Enantioselective Addition of α-Aminoalkyl Radicals to Isoquinolines

With a dual organocatalytic system involving a chiral phosphoric acid and a dicyanopyrazine-derived chromophore (DPZ) photosensitizer and under the irradiation with visible light, an enantioselective Minisci-type addition of α-amino acid-derived redox-active esters (RAEs) to isoquinolines has been developed. A variety of prochiral α-aminoalkyl radicals generated from RAEs were successfully introduced on isoquinolines, providing a range of valuable α-isoquinoline-substituted chiral secondary amines in high yields with good to excellent enantioselectivities.

Anthranilic acid based CCK1 receptor antagonists: Preliminary investigation on their second "touch point"

In this phase of structure-affinity relationship study of VL-0395, a new anthranilic acid based CCK1 selective antagonist, we propose a series of unnatural aminoacidic derivatives. The result of this work is the identification of a new CCK ligand, which possesses an affinity (IC50 = 35 nm) one order of magnitude greater than the lead and, as a general rule, it points out how the hypothesized receptorial pocket which accommodates the Phe residue allows much more structural modification than that interacting with the N-terminal group. Hence, the modification of the C-terminal pharmacophoric group of our lead VL-0395 can not only enhance the affinity of anthranilic acid derivatives but can modulate the selectivity for one CCK receptor subtype or afford mixed antagonists.

Ion channel modulating agents

The present invention relates to ion channel modulating agents. More particularly, the present invention relates to a particular class of chemical compounds that has proven useful as modulators of SK Ca, IK Ca and BK Ca channels. In further aspects, the present invention relates to the use of these SK/IK/BK channel modulating agents for the manufacture of medicaments, for methods of therapy, and pharmaceutical compositions comprising the SK/IK/BK channel modulating agents. The SK/IK/BK channel modulating agents of the invention are useful for the treatment or alleviation of diseases and conditions associated with the SK/IK/BK channels.

Synthetic and biotransformation studies on prochiral non-proteinogenic amino acids: Diethyl α-acetamido, α-alkylmalonates

Nine diethyl α-acetamido, α-alkylmalonates 3-11 (alkyl=methyl, benzyl, 3-fluorobenzyl, 4-fluorobenzyl, 2,6-difluorobenzyl, 3-trifluoromethylbenzyl, 4-trifluoromethylbenzyi, 2-chlorobenzyl and 3-chlorobenzyl) have been synthesised in three steps starting with diethyl malonate in overall yields of 49-90%. The structures of C-alkylated acetamidomalonates have been established on the basis of their speciral data, the structures of two compounds 9 and 11 are also confirmed on the basis of their X-ray crystallographic studies. Further, the X-ray crystal structure of the chiral monoethyl ester of α-acetamidomalonic acid 1 has been studied. None of our C-alkylated acetamidomalonate has been found to be a substrate for lipase-catalysed enantiodifferentiating deesterification/hydrolysis of the symmetric diester groups.
