Development of potent serotonin-3 (5-HT3) receptor antagonists. II. Structure-activity relationships of N-(1-benzyl-4-methylhexahydro-1H-1,4- diazepin-6-yl)carboxamides

Our studies on 4-amino-5-chloro-2-ethoxybenzamides led to the discovery that the N-(1,4-dimethylhexahydro-1H-1,4-diazepin-6-yl)benzamide 9 and the 1- benzyl-4-methylhexahydro-1H-1,4-diazepine analogue 10 are potent serotonin-3 (5-HT3) receptor antagonists. Structure-activity relationship (SAR) studies on the influence of the aromatic nucleus of 9 and 10 upon inhibition of the von Bezold-Jarisch reflex in rats are described. Heteroaromatic rings such as pyrrole, thiophene, furan, pyridine, pyridaziae, 1,2-benzisoxazole, indole, quinoline, and isoquinoline rings showed weak 5-HT3 receptor antagonistic activity. Within this series, use of the 1H-indazole ring as an aromatic moiety led to a substantial increase of the activity; the 1H- indazolylcarboxamides 54, 57, 97, and 102 showed potent 5-HT3 receptor antagonistic activity. The optimal compound identified via extensive SAR studies was N-(1-benzyl-4-methylhexahydro-1H-1,4-diazepin-6-yl)-1H-indazole- 3-carboxamide (54), whose effect was superior to that of the corresponding benzamide 10 and essentially equipotent to those of ondansetron (1) and granisetron (4).

Design, Synthesis, and Biological Evaluation of Amidobenzimidazole Derivatives as Stimulator of Interferon Genes (STING) Receptor Agonists

Stimulator of interferon genes (STING) is an endoplasmic reticulum-localized adaptor protein (STING receptor) that has been shown to be activated by binding to natural cyclic dinucleotide (CDN) ligands and plays a vital role in innate immune sensing of exogenous or endogenous DNA, which then induces type I interferons and other cytokines. In this paper, we described a series of amidobenzimidazole STING agonists with high potency for the STING receptor and presented the relevant structure-activity relationships (SARs). The relative potencies of compounds 16g, 24b, and 24e were measured by a STING competition binding assay. A more thorough study of the effect on the STING signaling pathway demonstrated that three compounds, 16g, 24b, and 24e, significantly increased the protein levels and mRNA levels of IFN-beta, CXCL10, and IL-6, and 24b as a representative compound effectively triggered the phosphorylation of STING, TBK1, and IRF3 in both human peripheral blood mononuclear cells (hPBMCs) and WT THP-1 cells. In addition, compound 24b demonstrated impressive antitumor efficacy in mice with established syngeneic colon tumors by intravenous administration. Furthermore, the pharmacokinetic profile of compound 24b was fully evaluated.

Fused Bicyclic Caspase-1 Inhibitors Assembled by Copper-Free Strain-Promoted Alkyne?Azide Cycloaddition (SPAAC)

Challenges exist in the development of potent and selective small-molecule inhibitors against caspase-1. Herein, by making use of the copper-free strain-promoted alkyne?azide cycloaddition (SPAAC) reaction between difluorinated cyclooctynes (DIFOs) and various azide-containing compounds, we showed for the first time that potential caspase-1 inhibitors could be rapidly synthesized. The resulting fused bicyclic compounds structurally resembled the central portion (P2?P3) of Pralnacasan (a well-known small molecule caspase-1 inhibitor), with diversity at the P4-position of the parental inhibitor conveniently installed from the azide component. Since our SPAAC-assembled inhibitor library was synthesized by using a copper-free bioorthogonal chemistry, the resulting 52-membered library (2 DIFOs¡Á26 azides) was immediately ready for subsequent cell-based screening for rapid identification of potential cell-permeable hits capable of effectively inhibiting endogenous caspase-1 activities. C1FS, a recently reported fluorogenic two-photon probe, which possesses improved live-cell imaging sensitivity against endogenous caspase-1, was used both in vitro and in LPS/ATP-induced macrophages (a well-established caspase-1-activated cell model) to screen against selected compounds from the above-mentioned library, leading to subsequent discovery of a novel caspase-1 inhibitor named b7-b.

Cholecystokinin antagonists: (R)-tryptophan-based hybrid antagonists of high affinity and selectivity for CCK-A receptors

The intriguing structural similarities of glutamic acid based cholecystokinin (CCK) antagonists (A-64718 and A-65186) and the benzodiazepine CCK antagonist MK-329 (L-364,718) have been reported. Efforts to include the weak CCK antagonist benzotript into this construct utilizing a similar approach have resulted in a novel series of benzotript-based hybrid antagonists N(alpha)-(3′-quinolylcarbonyl)-(R)-tryptophan di-n-pentylamide (9, A-67396), N(alpha)-(4′,8′-dihydroxy-2′-quinolylcarbonyl)-(R)-tryptophan di-n-pentylamide (23, A-70276), and N(alpha)-(3′-quinolylcarbonyl)-(R)-5′-hydroxytryptophan di-n-pentylamide (36, A-71134) which possess respectively binding affinities of 23, 21, and 11 nM for the pancreatic CCK-A receptor and which inhibit CCK8-induced amylase secretion. Compound 9 possesses a selectivity of > 500-fold for the pancreatic CCK-A receptor over the CCK-B receptor.

Synthesis and structure-activity relationships of potential anticonvulsants based on 2-piperidinecarboxylic acid and related pharmacophores

Using N-(2,6-dimethyl)phenyl-2-piperidinecarboxamide (1) and N-(alpha-methylbenzyl)-2-piperidinecarboxamide (2) as structural leads, a variety of analogues were synthesised and evaluated for anticonvulsant activity in the MES test in mice. In the N-benzyl series, introduction of 3-Cl, 4-Cl, 3,4-Cl2, or 3-CF3 groups on the aromatic ring led to an increase in MES activity. Replacement of the alpha-methyl group by either i-Pr or benzyl groups enhanced MES activity with no increase in neurotoxicity. Substitution on the piperidine ring nitrogen led to a decrease in MES activity and neurotoxicity, while reduction of the amide carbonyl led to a complete loss of activity. Movement of the carboxamide group to either the 3- or 4-positions of the piperidine ring decreased MES activity and neurotoxicity. Incorporation of the piperidine ring into a tetrahydroisoquinoline or diazahydrinone nucleus led to increased neurotoxicity. In the N-(2,6-dimethyl)phenyl series, opening of the piperidine ring between the 1- and 6-positions gave the active norleucine derivative 75 (ED50 = 5.8 mg kg-1, TD50 = 36.4 mg kg-1, PI = 6.3). Replacement of the piperidine ring of 1 by cycloalkane (cyclohexane, cyclopentane, and cyclobutane) resulted in compounds with decreased MES activity and neurotoxicity, whereas replacement of the piperidine ring by a 4-pyridyl group led to a retention of MES activity with a comparable PI. Simplification of the 2-piperidinecarboxamide nucleus of 1 into a glycinecarboxamide nucleus led to about a six-fold decrease in MES activity. The 2,6-dimethylanilides were the most potent compounds in the MES test in each group of compounds evaluated, and compounds 50 and 75 should be useful leads in the development of agents for the treatment of tonic-clonic and partial seizures in man.

Chemistry of ecteinascidins. Part 2. Preparation of 6?-O-acyl derivatives of stable ecteinascidin and evaluation of cytotoxicity

A large amount of stable ecteinascidin 770 (1b) was isolated from the Thai tunicate, Ecteinascidia thurstoni, which was pretreated with potassium cyanide in buffer solution (pH 7), along with a minor metabolite, ecteinascidin 786 (1c). A number of 6?-O-acyl derivatives 3-19 and three diacetyl derivatives 2a-c of the stable 1b were prepared and evaluated for activity against human tumor cell lines HCT116, QG56, and DU145. Nitrogen-containing heterocyclic ester derivatives such as 12, 13, and 16-19 showed similar in vitro cytotoxicity to 1b, whereas the other derivatives were less cytotoxic than 1b. Furthermore, we discovered that the N-indole-3-carbonyl derivative of ecteinascidin 770 (22) has higher cytotoxicity than 1b.

Synthesis and biological evaluation of quinoline-imidazole hybrids as potent telomerase inhibitors: A promising class of antitumor agents

A series of 1-isoquinoline-2-styryl-5-nitroimidazole derivatives has been synthesized and screened for telomerase inhibitory as well as antiproliferative properties on four variant cancer cell lines (U251, Hela, HepG-2 and A549). The bioassay results showed that most of the designed compounds exhibited moderate to potent in vitro inhibitory activity in the enzymatic and cellular assays, of which compounds 3u and 3v were revealed the most potent telomerase inhibitors, with IC50 values of 0.98 muM and 1.92 muM, respectively, compared to staurosporine. Docking simulation was performed to position compounds 3u and 3v into the telomerase active site to determine the probable binding pose. Twenty three compounds were scrutinized by the CoMFA and CoMSIA techniques of 3D Quantitative Structure-Activity Relationship (QSAR). These new findings along with molecular docking observations could provide important information that compounds 3u and 3v with potent inhibitory activity in tumor growth inhibition may be potential anticancer agents.
