Inhibition Mechanisms of a Pyridazine-Based Amyloid Inhibitor: As a beta-Sheet Destabilizer and a Helix Bridge Maker

Conformational diseases have been investigated extensively in recent years; as a result, a number of drug candidates have been introduced as amyloid inhibitors; however, no effective therapies have been put forward. RS-0406 with pyridazine as its core chemical structure has so far shown promising results in inhibiting amyloid formation. In the present work, using molecular dynamics, we undertook the investigation of RS-0406 interactions with U-shaped A beta(1-42) and A beta(1-40) pentamers, A beta(1-42) monomers, and double-horseshoe-like A beta(1-42). To set better parameters for the small molecule, experimental and computational log?P values were obtained. In addition, an analogue of RS-0406 was also simulated for comparison. The results indicate that RS-0406 may inhibit amyloid formation exploiting two different mechanisms. One mechanism includes stabilizing the alpha helix, in the monomer peptide, by binding to the flanking sites of the amyloidogenic region. The second mechanism mediates through interaction of the small molecules near the amyloidogenic regions, leading to destabilization of the beta-sheets in both the U-shaped and the S-shaped fibril. Notably, a persistent interaction between the imidazole ring of His14 from an S-shaped structure and the pyridazine ring of RS-0406 was observed. The unique structural properties of RS-0406, including aromaticity, H-bonding capability, flexibility, and symmetry, allow the small molecule to noticeably affect amyloid formation.

Discovery of BMS-986260, a Potent, Selective, and Orally Bioavailable TGF beta R1 Inhibitor as an Immuno-oncology Agent

Novel imidazole-based TGF beta R1 inhibitors were identified and optimized for potency, selectivity, and pharmacokinetic and physicochemical characteristics. Herein, we report the discovery, optimization, and evaluation of a potent, selective, and orally bioavailable TGF beta R1 inhibitor, 10 (BMS-986260). This compound demonstrated functional activity in multiple TGF beta-dependent cellular assays, excellent kinome selectivity, favorable pharmacokinetic properties, and curative in vivo efficacy in combination with anti-PD-1 antibody in murine colorectal cancer (CRC) models. Since daily dosing of TGF beta R1 inhibitors is known to cause class-based cardiovascular (CV) toxicities in preclinical species, a dosing holiday schedule in the anti-PD-1 combination efficacy studies was explored. An intermittent dosing regimen of 3 days on and 4 days off allowed mitigation of CV toxicities in one month dog and rat toxicology studies and also provided similar efficacy as once daily dosing.

Developing pyridazine-3-carboxamides to be CB2 agonists: The design, synthesis, structure-activity relationships and docking studies

Herein, we described the design and synthesis of a series of pyridazine-3-carboxamides to be CB2-selective agonists via a combination of scaffold hopping and bioisosterism strategies. The compounds were subjected to assessment of their potential activities through calcium mobilization assays. Among the tested derivatives, more than half of these compounds exhibited moderate to potent CB2 agonist activity. Six compounds showed EC50 values below 35 nM, and several derivatives also exhibited significantly enhanced potency and high selectivity at the CB2 receptor over the CB1 receptor. Specifically, compound 26 showed the highest CB2 agonist activity (EC50 = 3.665 +/- 0.553 nM) and remarkable selectivity (Selectivity Index > 2729) against CB1. In addition, logPs of some representative compounds were measured to display significantly decreased values in comparison with GW842166X. Furthermore, docking simulations were conducted to explain the interaction mode of this series. (C) 2017 Elsevier Masson SAS. All rights reserved.

Evidence That Sedative Effects of Benzodiazepines Involve Unexpected GABA(A) Receptor Subtypes: Quantitative Observation Studies in Rhesus Monkeys

In nonhuman primates we tested a new set of behavioral categories for observable sedative effects using pediatric anesthesiology classifications as a basis. Using quantitative behavioral observation techniques in rhesus monkeys, we examined the effects of alprazolam and diazepam (nonselective benzodiazepines), zolpidem (preferential binding to alpha 1 subunit-containing GABA(A) receptors), HZ-166 (8-ethynyl-6-(2′-pyridine)-4H-2,5,10b-triaza-benzo[e]azulene-3-carboxylic acid ethyl ester; functionally selective with relatively high intrinsic efficacy for alpha 2 and alpha 3 subunit-containing GABA(A) receptors), MRK-696 [7-cyclobutyl-6-(2-methyl-2H-1,2,4-triazol-2-ylmethoxy)-3-(2-flurophenyl)-1,2,4-triazolo(4,3-b) pyridazine; no selectivity but partial intrinsic activity], and TPA023B 6,2′-diflouro-5′-[3-(1-hydroxy-1-methylethyl)imidazo[1,2-b][1,2,4]triazin-7-yl]biphenyl-2-carbonitrile; partial intrinsic efficacy and selectivity for alpha 2, alpha 3, alpha 5 subunit-containing GABA(A) receptors]. We further examined the role of alpha 1 subunit-containing GABA(A) receptors in benzodiazepine-induced sedative effects by pretreating animals with the alpha 1 subunit-preferring antagonist beta-carboline-3-carboxylate-t-butyl ester (beta CCT). Increasing doses of alprazolam and diazepam resulted in the emergence of observable ataxia, rest/sleep posture, and moderate and deep sedation. In contrast, zolpidem engendered dose-dependent observable ataxia and deep sedation but not rest/sleep posture or moderate sedation, and HZ-166 and TPA023 induced primarily rest/sleep posture. MRK-696 induced rest/sleep posture and observable ataxia. Zolpidem, but no other compounds, significantly increased tactile/oral exploration. The sedative effects engendered by alprazolam, diazepam, and zolpidem generally were attenuated by beta CCT pretreatments, whereas rest/sleep posture and suppression of tactile/oral exploration were insensitive to beta CCT administration. These data suggest that alpha 2/3-containing GABA(A) receptor subtypes unexpectedly may mediate a mild form of sedation (rest/sleep posture), whereas alpha 1-containing GABA(A) receptors may play a role in moderate/deep sedation.

Design, Synthesis, and Molecular Mechanism Studies of N-Phenylisoxazoline-thiadiazolo[3,4-a]pyridazine Hybrids as Protoporphyrinogen IX Oxidase Inhibitors

Protoporphyrinogen oxidase (PPO, EC 1.3.3.4) is an important target for green agrochemical discovery. Herein, a novel N-phenylisoxazoline-thiadiazolo[3,4-a]pyridazine herbicidal active scaffold was designed by the scaffold hybridization strategy. Systematic structural optimization enabled the discovery of a series of derivatives with excellent weed control at 9.375-150 g ai/ha by the post-emergent application. Some derivatives exhibited improved Nicotiana tabacum PPO (NtPPO)-inhibitory activity than fluthiacet-methyl. Of these, 2b, with K-i = 21.8 nM, displayed higher weed control than fluthiacet-methyl at the rate of 12-75 g ai/ha, and selective to maize at 75 g ai/ha. In planta, 2b was converted into a bioactive metabolite S (K-i = 4.6 nM), which exhibited 4.6-fold more potency than 2b in inhibiting the activity of NtPPO. Molecular dynamics simulation explained that 5 formed stronger pi-pi interaction with Phe392 than that of 2b. This work not only provides a promising lead compound for weed control in maize fields but is also helpful to understand the molecular mechanism and basis of the designed hybrids.
