Synthesis and Structure Activity Relationship of Pyridazine-Based Inhibitors for Elucidating the Mechanism of Amyloid Inhibition

Conformational diseases, constituting a large number of diseases, have been connected with protein misfolding, leading to aggregation known as amyloid fibrils. Mainly due to the lack of detailed molecular mechanisms, there has not been an effective drug to combat amyloid-associated diseases. Recently, a small organic pyridazine-based molecule (RS-0406) has shown significant reductions in amyloid fibrils in both in vitro and in vivo animal studies. However, no information on molecular details of inhibition for the small molecule has been reported. In this work, we have decided to explore structure-activity relationship of pyridazine-based compounds to investigate structural parameters for amyloid inhibition. A number of closely related derivatives of RS-0406 were designed and synthesized to delineate the roles of structural properties, including bulkiness and halogen bonding, hydrogen-bonding ability, and the position of substituents on the flanking aromatic rings of the synthetic molecules. To examine the effectiveness of the synthesized compounds, amyloid fibril formation of hen egg white lysozyme was measured in the presence of each synthetic molecule. Our results indicated that in addition to the type of the aryl substituent, their positions on the ring were also important for their inhibitory roles in amyloid fibrils formation. Moreover, a fluorinated compound turned out to be a more effective kinetic inhibitor, displaying a delayed fibril nucleation than the original lead compound. Furthermore, biochemical structural analyses and molecular dynamics simulation revealed that the pyridazine-based compounds may mediate the inhibition of amyloid fibrils through stabilization of the protein monomer during partially unfolded state. The cytotoxicity assay revealed that the amounts of amyloid intermediates were reduced in the presence of the synthetic compounds. Eventually, IC50 values were obtained for the synthetic compounds, and quantitative structure-activity relationship method was employed to suggest more effective amyloid inhibitors.

Contributions of organic electrosynthesis to green chemistry

In organic electrosynthesis C-C bond formation and functional group interconversion proceed via reactive intermediates that are generated by electron transfer at the anode and cathode. Electron transfer combined with a chemical reaction provides conversions that are not available in non-electrochemical reactions. These are potential selectivity, redox-umpolung, and the substitution of a hydrogen atom for a nucleophile or the addition of two nucleophiles to a double bond in one-pot reactions. Furthermore electrolysis is well suited for oxidation and reduction of functional groups. Electrochemical syntheses need mostly fewer steps, produce less waste, provide a cheaper reagent, require less auxiliaries and allow often an easier scale-up than non-electrochemical syntheses. In addition, they can be conducted at ambient temperature and pressure. All these qualities agree well with the rules of green chemistry. This statement is substantiated with examples of C-C bond formation and functional group interconversion at the anode and cathode.

Discovery of piperazin-1-ylpyridazine-based potent and selective stearoyl-CoA Desaturase-1 inhibitors for the treatment of obesity and metabolic syndrome

Stearoyl-CoA desaturase-1 (SCD1) catalyzes de novo synthesis of monounsaturated fatty acids from saturated fatty acids. Studies have demonstrated that rodents lacking a functional SCD1 gene have an improved metabolic profile, including reduced weight gain, lower triglycerides, and improved insulin response. In this study, we discovered a series of piperazinylpyridazine-based highly potent, selective, and orally bioavailable compounds. Particularly, compound 49 (XEN103) was highly active in vitro (mSCD1 IC50 = 14 nM and HepG2 IC50 = 12 nM) and efficacious in vivo (ED50 = 0.8 mg/kg). It also demonstrated striking reduction of weight gain in a rodent model. Our findings with small-molecule SCD1 inhibitors confirm the importance of this target in metabolic regulation, describe novel models for assessing SCD1 inhibitors for efficacy and tolerability and demonstrate an opportunity to develop a novel therapy for metabolic disease.

Optimization of an imidazopyridazine series of inhibitors of plasmodium falciparum calcium-dependent protein kinase 1 (Pf CDPK1)

A structure-guided design approach using a homology model of Plasmodium falciparum calcium-dependent protein kinase 1 (PfCDPK1) was used to improve the potency of a series of imidazopyridazine inhibitors as potential antimalarial agents. This resulted in high affinity compounds with PfCDPK1 enzyme IC 50 values less than 10 nM and in vitro P. falciparum antiparasite EC50 values down to 12 nM, although these compounds did not have suitable ADME properties to show in vivo efficacy in a mouse model. Structural modifications designed to address the ADME issues, in particular permeability, were initially accompanied by losses in antiparasite potency, but further optimization allowed a good balance in the compound profile to be achieved. Upon testing in vivo in a murine model of efficacy against malaria, high levels of compound exposure relative to their in vitro activities were achieved, and the modest efficacy that resulted raises questions about the level of effect that is achievable through the targeting of PfCDPK1.

Synthesis and stereoselective C-C bond-forming reactions of peptide aldehydes

The reaction of the activated form of N-protected amino acids 6 and 10 or peptides 14 and 18 with chiral amino alcohols derived from the corresponding alpha-amino acids affords peptide alcohols which can be oxidized under Swern conditions to produce the corresponding peptide aldehydes 9, 12, 16 and 20. The rational synthesis of diastereomeric di- and tripeptide aldehydes, e.g., (S,S)- or (R,S)-dipeptides as well as (S,S,S)- or (R,S,S)-tripeptides is possible by proper choice of the respective building blocks [(S)- versus (R)-amino acids]. The compounds can be prepared without any undesired alpha-epimerization. However, the long-term configurational stability depends upon the configuration at the remote stereogenic center, e.g., (R,S)-dipeptide aldehydes epimerize faster than the (S,S) diastereomers. Di- and tripeptide aldehydes 9, 12, 16 and 20 undergo chelation-controlled Grignardtype additions with Me2CuLi that involve little or no undesired alpha-epimerization. The (S,S)- and (R,S)-dipeptide aldehydes 9 and 12 undergo chelation-controlled pinacol reactions induced by the low-valent vanadium reagent [V2Cl3(THF)6]2[Zn2Cl 6]. The major products in both cases are the corresponding C2-symmetric diols 33 and 36, respectively, which are of interest as potential HIV-protease inhibitors. The degree of stereoselectivity is significantly higher in the case of the (S,S)-dipeptide aldehydes relative to the (R,S) analogs, an observation which can be explained on the basis of three-point binding of the peptides to vanadium.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 3-Phenyl-6-chloropyridazine, you can also check out more blogs about20375-65-9

Synthesis, radiolabeling and in vivo evaluation of [11C](R)-1- [4-[2-(4-methoxyphenyl)phenyl]piperazin-1-yl]-3-(2-pyrazinyloxy)-2-propanol, a potential PET radioligand for the 5-HT7receptor

In the search for a novel serotonin 7 (5-HT7) receptor PET radioligand we synthesized and evaluated a new series of biphenylpiperazine derivatives in vitro. Among the studied compounds, (R)-1-[4-[2-(4-methoxyphenyl) phenyl]piperazin-1-yl]-3-(2-pyrazinyloxy)-2-propanol ((R)-16), showed the best combination of affinity, selectivity, and lipophilicity, and was thus chosen for carbon-11 labelling and evaluation in pigs. After intravenous injection, [11C](R)-16 entered the pig brain and displayed reversible tracer kinetics. Pretreatment with the 5-HT7receptor selective antagonist SB-269970 (1) resulted in limited decrease in the binding of [11C](R)-16, suggesting that this radioligand is not optimal for imaging the brain 5-HT7receptor in vivo but it may serve as a lead compound for the design of novel 5-HT7receptor PET radioligands.
