Synthesis and antihypertensive activity of new 6-heteroaryl-3-hydrazinopyridazine derivatives

The synthesis and pharmacological activity of new 6-heteroaryl-3-hydrazinopyridazines with antihypertensive action are described. The introduction of pyrrole, pyrazole, imidazole, triazole, tetrazole, thiophene, indole, and carbazole heterocyclic rings into the 6 position of the pyridazine nucleus has been carried out by three different methods of synthesis. The hypotensive action has been examined on normotensive and spontaneously hypertensive rats by comparison with dihydralazine (I). 6-Imidazol-1-yl derivatives have proved particularly active. Of these derivatives 3-hydrazino-6-(2-methylimidazol-1-yl)pyridazine (7c) achieves 4.9 times the activity of dihydralazine when administered orally to spontaneously hypertensive rats. The LD50 values of 7c and dihydralazine are very similar.

An efficient solid-phase synthesis of peptidyl-N-acetylguanidines for use in native chemical ligation

In the modern protocols of chemical protein syntheses, peptide-alpha-thioesters have been used as key components for the assembly of full-length polypeptides through chemoselective peptide coupling reactions. A variety of thioester precursors have been developed for the synthesis of the peptide-alpha-thioesters by Fmoc solid phase peptide synthesis (Fmoc-SPPS). Recently our group found a peptidyl-N-acetylguanidine as a new peptide-alpha-thioester precursor. This peptide derivative can be converted into a corresponding peptide-alpha-thioester only by treatment with an excess amount of a thiol in aqueous buffers at around neutral pH. This unique property allowed us to envision the practical use of the peptidyl-N-acetylguanidines for the chemical syntheses of proteins; however, an efficient synthetic method has been lacking. Herein, we report an efficient solid-phase synthesis of peptidyl-N-acetylguanidines. This new synthetic method employing selective activation and cleavage of a peptide bond successfully provided peptidyl-N-acetylguanidines from the on-resin protected peptides prepared by standard Fmoc-SPPS. We also evaluated the reactivity of a peptidyl-N-acetylguanidine in native chemical ligation through the synthesis of glucose-dependent insulinotropic polypeptide analogue.

An efficient biosensor for monitoring Alzheimer’s disease risk factors: Modulation and disaggregation of the Abeta aggregation process

Alzheimer’s disease (AD) is a progressive neurodegenerative disease, which can lead to the complete loss of cognition. Cu2+ and H2S are both correlated with the physiological and pathological events of AD. Therefore, suitable methods to continuously monitor Cu2+ and H2S are in great demand for a better understanding of the detailed mechanism of Alzheimer’s disease. Based on the heteroatom (N, O, and S) competitive effect, a series of reversible “off-on-off” fluorescent probes, S1-S3, for the detection of Cu2+ and H2S was designed and synthesized, which contain different alkaloids as acceptors. Their mechanism is demonstrated via IR spectroscopy, Job plot analysis and DFT calculation. These three compounds exhibited high selectivity and sensitivity (limit of detection = 1.95 nM, 1.51 nM, and 6.62 nM, respectively) for Cu2+ with a fast response rate. In addition, S1 exhibited extremely low cytotoxicity and superb membrane permeability, which could be applied in living MCF-7 cells and living mice to monitor Cu2+ under physiological conditions. Importantly, the excellent chelation of the S1 probe for Cu2+ was effectively utilized to capture Cu2+ from the aggregation of Abeta, which was observed experimentally via ThT fluorescence, transmission electron microscopy (TEM), and native polyacrylamide gel electrophoresis (native-PAGE).

Broadening of the substrate tolerance of alpha-chymotrypsin by using the carbamoylmethyl ester as an acyl donor in kinetically controlled peptide synthesis

In the kinetically controlled approach of peptide synthesis mediated by alpha-chymotrypsin, the broadening of the protease’s substrate tolerance is achieved by switching the acyl donor from the conventional methyl ester to the carbamoylmethyl ester. Thus, as a typical example, the extremely low coupling efficiency obtained by employing the methyl ester of an inherently poor amino acid substrate, Ala, is significantly improved by the use of this particular ester. Its ameliorating effect is observed also in the couplings of other amino acid residues such as Gly and Ser as carboxy components.
