Design, synthesis, and evaluation of inhibitors for severe acute respiratory syndrome 3C-like protease based on phthalhydrazide ketones or heteroaromatic esters

The 3C-like protease (3CLpro), which controls the severe acute respiratory syndrome (SARS) coronavirus replication, has been identified as a potential target for drug design in the treatment of SARS. A series of tetrapeptide phthalhydrazide ketones, pyridinyl esters, and their analogs have been designed, synthesized, and evaluated as potential SARS 3CLpro inhibitors. Some pyridinyl esters are identified as very potent inhibitors, with IC50 values in the nanomolar range (50-65 nM). Electrospray mass spectrometry indicates a mechanism involving acylation of the active site cysteine thiol for this class of inhibitors.

Identification of benzothiophene amides as potent inhibitors of human nicotinamide phosphoribosyltransferase

Nicotinamide phosphoribosyltransferase (Nampt) is an attractive therapeutic target for cancer. A Nampt inhibitor with novel benzothiophene scaffold was discovered by high throughput screening. Herein the structure-activity relationship of the benzothiophene Nampt inhibitor was investigated. Several new inhibitors demonstrated potent activity in both biochemical and cell-based assays. In particular, compound 16b showed good Nampt inhibitory activity (IC50= 0.17 muM) and in vitro antitumor activity (IC50= 3.9 muM, HepG2 cancer cell line). Further investigation indicated that compound 16b could efficiently induce cancer cell apoptosis. Our findings provided a good starting point for the discovery of novel antitumor agents.

Discovery of a Novel Class of Negative Allosteric Modulator of the Dopamine D2 Receptor Through Fragmentation of a Bitopic Ligand

Recently, we have demonstrated that N-((trans)-4-(2-(7-cyano-3,4-dihydroisoquinolin-2(1H)-yl)ethyl)cyclohexyl)-1H-indole-2-carboxamide (SB269652) (1) adopts a bitopic pose at one protomer of a dopamine D2 receptor (D2R) dimer to negatively modulate the binding of dopamine at the other protomer. The 1H-indole-2-carboxamide moiety of 1 extends into a secondary pocket between the extracellular ends of TM2 and TM7 within the D2R protomer. To target this putative allosteric site, we generated and characterized fragments that include and extend from the 1H-indole-2-carboxamide moiety of 1. N-Isopropyl-1H-indole-2-carboxamide (3) displayed allosteric pharmacology and sensitivity to mutations of the same residues at the top of TM2 as was observed for 1. Using 3 as an “allosteric lead”, we designed and synthesized an extensive fragment library to generate novel SAR and identify N-butyl-1H-indole-2-carboxamide (11d), which displayed both increased negative cooperativity and affinity for the D2R. These data illustrate that fragmentation of extended compounds can expose fragments with purely allosteric pharmacology.

Ligand-free Pd-catalysed decarboxylative arylation of imidazo[1,2-: A] pyridine-3-carboxylic acids with aryl bromides

A facile ligand-free method for Pd(OAc)2 catalysed decarboxylative arylation of imidazo[1,2-a]pyridine-3-carboxylic acids with hetero(aryl) bromides has been developed. This method is applicable to a variety of (hetero)aryl bromides as coupling partners. Electron withdrawing and donating groups on imidazo[1,2-a]pyridine-3-carboxylic acids are well tolerated. It represents the first general protocol for ligand-free Pd(OAc)2 catalysed decarboxylative arylation of imidazo[1,2-a]pyridine-3-carboxylic acids with (hetero)aryl halides. A few of the compounds synthesized using this protocol showed antibacterial activity against Staphylococcus aureus.

Structure-affinity relationship study on N-[4-(4-arylpiperazin-1-yl)butyl]arylcarboxamides as potent and selective dopamine D3 receptor ligands

The benzamide PB12 (N- [2-[4-(4-chlorophenyl)piperazin-1-yl] ethyl]-3-methoxybenzamide) (1), already reported as potent and selective dopamine D4 receptor ligand, has been modified searching for structural features that could lead to D3 receptor affinity. Changes in the aromatic ring linked to N-1 piperazine ring led to the identification of 2-methoxyphenyl and 2,3-dichlorophenyl derivatives (compounds 6 and 13) displaying moderate D3 affinity (Ki = 145 and 31 nM, respectively). Intermediate alkyl chain elongation in compounds 1, 6, and 13 improved binding affinity for the D3 receptor and decreased the D4 affinity (compounds 18-26). Among these latter compounds, the N-[4-[4-(2,3-dichlorophenyl)piperazin-1-yl]butyl]-3- methoxybenzamide (19) was further modified with the replacement or of the 2,3-dichlorophenyl moiety (compounds 27-30) or of the 3-methoxyphenyl ring (compounds 31-41). In this way, we identified several high-affinity D3 ligands (0.13 nM < Ki's < 4.97 nM) endowed with high selectivity over D2, D4, 5-HT1A, and alpha1 receptors. In addition, N-[4-[4-(2,3-dimethylphenyl)- piperazin-1-yl]butyl]-3-methoxybenzamide (27) and N-[4-[4-(2,3-dichlorophenyl)piperazin-1-yl]- butyl]-7-methoxy-2-benzofurancarboxamide (41) appear to be valuable candidates for positron emission tomography (PET) because of their affinity values, lipophilicity properties, and liability of 11C labeling in the O-methyl position.

Reversible small molecule inhibitors of MAO A and MAO B with anilide motifs

Background: Ligands consisting of two aryl moieties connected via a short spacer were shown to be potent inhibitors of monoamine oxidases (MAO) A and B, which are known as suitable targets in treatment of neurological diseases. Based on this general blueprint, we synthesized a series of 66 small aromatic amide derivatives as novel MAO A/B inhibitors. Methods: The compounds were synthesized, purified and structurally confirmed by spectroscopic methods. Fluorimetric enzymological assays were performed to determine MAO A/B inhibition properties. Mode and reversibility of inhibition was determined for the most potent MAO B inhibitor. Docking poses and pharmacophore models were generated to confirm the in vitro results. Results: N-(2,4-Dinitrophenyl)benzo[d][1,3]dioxole-5-carboxamide (55, ST-2043) was found to be a reversible competitive moderately selective MAO B inhibitor (IC50 = 56 nM, Ki = 6.3 nM), while N-(2,4-dinitrophenyl)benzamide (7, ST-2023) showed higher preference for MAO A (IC50 = 126 nM). Computational analysis confirmed in vitro binding properties, where the anilides examined possessed high surface complementarity to MAO A/B active sites. Conclusion: The small molecule anilides with different substitution patterns were identified as potent MAO A/B inhibitors, which were active in nanomolar concentrations ranges. These small and easily accessible molecules are promising motifs, especially for newly designed multitargeted ligands taking advantage of these fragments.
