Selective Toll-like receptor 7 agonists with novel chromeno[3,4-d]imidazol-4(1H)-one and 2-(trifluoromethyl)quinoline/ quinazoline-4-amine scaffolds

Toll-like receptors (TLRs) are promising targets for treatment of viral infections, autoimmune diseases, and cancers. Here, two new series of selective small-molecule TLR7 agonists with novel scaffolds and good selectivity over TLR8 are described, some with potencies in the low micromolar range. 8-Hydroxy-1-isobutylchromeno[3,4-d]imidazol-4(1H)-one (26) from the first series was designed and synthesized on the basis of previously described TLR7 antagonist 2, and is shown to be a selective TLR7 agonist (EC50, 1.8 muM). The second series was based on 2-(trifluoromethyl)quinolin-4-amine and 2-(trifluoromethyl)quinazolin-4-amine scaffolds, which were defined according to our in-house ligand-based virtual screening protocol. Further synthesis of a focused library of analogs, biological evaluation, and docking studies provided systematic exploration of the structure?activity relationships, which indicate that a secondary or tertiary amine with smaller flexible alkyl substituents up to three carbon atoms in length, or bulkier rigid aliphatic rings is required at position 4 on 2-(trifluoromethyl)quinoline/quinazoline scaffold for potent TLR7 agonist activity. The influence of selected TLR7 agonists on cytokine production is also reported showing that N-cyclopropyl-2-(trifluoromethyl)quinazolin-4-amine (46) is able to induce increased levels of IL-6 and IL-8. These data demonstrate successful in-silico definition of novel TLR7 versus TLR8-selective compounds as promising chemical probes for further development of potent small-molecule immunomodulators.

Optically active 1,3,4,4-tetrasubstituted beta-lactams: Synthesis and evaluation as tumor cell growth inhibitors

The in vitro cytotoxicity assays of several enantiopure (3S,4S)- and (3R,4R)-1,3,4,4-tetrasubstituted beta-lactams derived from amino acids have shown that the (3S,4S)-4-benzyl-1-p-methoxybenzyl-3-methyl-4-methoxycarbonyl derivative 2a, obtained from Phe, displays significant activity, which is comparable to that of the anticancer drug Doxorubicin against HT29 cell lines. Modifications at positions 1 and 4 of the beta-lactam ring led to identify the Tyr(2,6-ClBz) analogu 26d with similar activity data to those of 2a. The synthesis and SAR of all these tetrasubstituted beta-lactams are reported here.

Synthesis, photophysical and cytotoxicity evaluations of DNA targeting agents based on 3-amino-1,8-naphthalimide derived Troeger’s bases

The synthesis and characterisation of five bis-1,8-naphthalimide containing Troeger’s bases 1-5 formed from their corresponding 3-amino-1,8- naphthalimide precursors 6-10 is described. The photophysical investigations of 1-5 and 6-10 were carried out in several organic solvents as well as in water and as a function of pH using UV-Vis absorption and fluorescence spectroscopies. The DNA binding affinities of 1-5 in aqueous solution at pH 7.4 were also investigated using several UV-Vis absorption and fluorescence experiments by using calf thymus DNA (ct-DNA). These molecules exhibited significant DNA binding affinities; where large binding values (Kb) in the range of 106 M-1 were determined, even in competitive media (50 mM and 160 mM NaCl at pH 7.4). Thermal denaturation measurements also showed that 1-5 significantly stabilised the DNA helix. Using linear and circular dichroism we further demonstrated that the DNA binding interaction occurs both by intercalation and by groove binding. The Troeger’s bases were further shown to be rapidly taken up into cells using confocal fluorescence spectroscopy; and cytotoxic studies in HeLa and MCF-7 cells showed that most of the Troeger’s bases were effective cytotoxic agents with EC50 values of between 1.1-12 muM and that all the active compounds induced programmed cell death by apoptosis, where up to 70% cellular death was observed after 24 h of incubation for 4.

Studies on pyrazine derivatives, XLVI: The synthesis of new pyrazine derivatives with N?-(pyrazine-2-carbonyl)-hydrazinecarbodithioic acid methyl ester usage

4-Omega-alkylsubstituted derivatives of 1,2,4-triazole-2-thiones 2-7 were obtained using the high reactivity of N?-(pyrazine-2-carbonyl)- hydrazinecarbodithioic acid methyl ester 1 towards amines. In the reaction with cysteamine 1,3-thiazaethylene-1,2,4-triazole 8 formed. Aromatic amines and N-aminocycloalkylamines gave thiosemicarbazide derivatives 9-12 under the same conditions. The solution of sodium hydroxide caused the decomposition of compounds 11 and 12 and resulted in 4-piperidino- and 4-morpholino- thiosemicarbazides 13 and 14. Compounds 11 and 12 were cyclized to appropriate 4-substituted 1,2,4-triazole-2-thiones 16 and 17 under the influence of DBU or potassium carbonate solution. The heating of derivative 12 with sulfuric acid led to disubstituted 1,3,4-thiadiazole 18. Copyright Taylor & Francis Group, LLC.

Antitumor agents. 148. Synthesis and biological evaluation of novel 4 beta-amino derivatives of etoposide with better pharmacological profiles.

A series of novel 4 beta-amino derivatives of etoposide (1), which can form water-soluble salts and demonstrate excellent activity against mdr- and topo II-resistant cell lines, have been synthesized. Compared with etoposide, compounds 5-6, 8, and 10-16 show comparable or greater inhibition of human DNA topo II. In a cellular protein-DNA complex formation assay, compounds 5-6, 8, 10-14, and 16 are more potent than 1. A dose-response study of 8 shows that it is 20 times more active in formation of protein-linked DNA breaks than etoposide. Furthermore, both 8 and its free base 7 were found to be highly active toward etoposide-resistant KB cell lines. All compounds were also evaluated in vitro against a total of 56 human tumor cell lines derived from seven cancer types. Comparison of the log10 GI50 mean graph midpoints of 5-19 (-4.89 to -7.30) with that of 1 (-4.08) shows these new analogs to be 6-1659-fold more active than 1.

Insights into the mechanism of inhibition of CXCR4: Identification of piperidinylethanamine analogs as anti-HIV-1 inhibitors

The cellular entry of HIV-1 into CD4+ T cells requires ordered interactions of HIV-1 envelope glycoprotein with C-X-C chemokine receptor type 4 (CXCR4) receptors. However, such interactions, which should be critical for rational structure-based discovery of new CXCR4 inhibitors, remain poorly understood. Here we first determined the effects of amino acid substitutions in CXCR4 on HIV-1NL4-3 glycoprotein-elicited fusion events using site-directed mutagenesis-based fusion assays and identified 11 potentially key amino acid substitutions, including D97A and E288A, which caused >30% reductions in fusion. We subsequently carried out a computational search of a screening library containing?604,000 compounds, in order to identify potential CXCR4 inhibitors. The computational search used the shape of IT1t, a known CXCR4 inhibitor, as a reference and employed various algorithms, including shape similarity, isomer generation, and docking against a CXCR4 crystal structure. Sixteen small molecules were identified for biological assays based on their high shape similarity to IT1t, and their putative binding modes formed hydrogen bond interactions with the amino acids identified above. Three compounds with piperidinylethanamine cores showed activity and were resynthesized. One molecule, designated CX6, was shown to significantly inhibit fusion elicited by X4 HIV-1NL4-3 glycoprotein (50% inhibitory concentration [IC50], 1.9 muM), to inhibit Ca2+ flux elicited by stromal cell-derived factor 1alpha (SDF-1alpha) (IC50, 92 nM), and to exert anti-HIV-1 activity (IC50, 1.5 muM). Structural modeling demonstrated that CX6 bound to CXCR4 through hydrogen bond interactions with Asp97 and Glu288. Our study suggests that targeting CXCR4 residues important for fusion elicited by HIV-1 envelope glycoprotein should be a useful and feasible approach to identifying novel CXCR4 inhibitors, and it provides important insights into the mechanism by which small-molecule CXCR4 inhibitors exert their anti-HIV-1 activities.
