- α-Amino Acid-Isosteric α-Amino Tetrazoles
-
The synthesis of all 20 common natural proteinogenic and 4 otherα-amino acid-isosteric α-amino tetrazoles has been accomplished, whereby the carboxyl group is replaced by the isosteric 5-tetrazolyl group. The short process involves the use of the key Ugi tetrazole reaction followed by deprotection chemistries. The tetrazole group is bioisosteric to the carboxylic acid and is widely used in medicinal chemistry and drug design. Surprisingly, several of the common α-amino acid-isosteric α-amino tetrazoles are unknown up to now. Therefore a rapid synthetic access to this compound class and non-natural derivatives is of high interest to advance the field.

- Discovery of α-Substituted Imidazole-4-acetic Acid Analogues as a Novel Class of ρ1γ-Aminobutyric Acid Type A Receptor Antagonists with Effect on Retinal Vascular Tone
-
The ρ-containing γ-aminobutyric acid type A receptors (GABAARs) play an important role in controlling visual signaling. Therefore, ligands that selectively target these GABAARs are of interest. In this study, we demonstrate that the partial GABAAR agonist imidazole-4-acetic acid (IAA) is able to penetrate the blood–brain barrier in vivo; we prepared a series of α- and N-alkylated, as well as bicyclic analogues of IAA to explore the structure–activity relationship of this scaffold focusing on the acetic acid side chain of IAA. The compounds were prepared via IAA from l-histidine by an efficient minimal-step synthesis, and their pharmacological properties were characterized at native rat GABAARs in a [3H]muscimol binding assay and at recombinant human α1β2γ2Sand ρ1GABAARs using the FLIPR membrane potential assay. The (+)-α-methyl- and α-cyclopropyl-substituted IAA analogues ((+)-6 a and 6 c, respectively) were identified as fairly potent antagonists of the ρ1GABAAR that also displayed significant selectivity for this receptor over the α1β2γ2SGABAAR. Both 6 a and 6 c were shown to inhibit GABA-induced relaxation of retinal arterioles from porcine eyes.

- trans-4-Methyl-3-imidazoyl pyrrolidine as a potent, highly selective histamine H3 receptor agonist in vivo
-
Extensive structural modification of immepyr (+)-2 led to the dsiscovery of trans-4-methyl-3-imidazoyl pyrrolidine (±)-3a as a potent and highly selective H3 agonist. The pyrroline (±)-3a was resolved, and its (+) enantiomer, Sch 50971 [(+)-3a], showed a greater separation of H3 and H1 activities in vivo (H3/H1 ratio >> 330) than (R)-α-methylhistamine (+)-1 (H3/H1 ratio = 17), the standard H3 agonist.

- A new type of carboxypeptidase A inhibitors designed using an imidazole as a zinc coordinating ligand
-
2-(4-Imidazoyl)hydrocinnamic acid (1) and its congeners (2-4) having different length of alkyl chain spacers between the imidazole ring and the α-carbon to the carboxylate of 1 have been designed, synthesized and evaluated as inhibitors for carboxypeptidase A to show that they are competitive inhibitors for the enzyme. Inhibitor 1 was most potent having the K(i) value of 0.8 μM. The present study demonstrates that imidazole ring is an effective zinc coordinating ligand that can be useful for the design of inhibitors for zinc proteases.
