Using a single drug to treat cancer with dual-targeting is an unusual approach when compared to other drug combinations. Dual-targeting agents were developed as a result of insufficient efficacy and drug resistance when single-targeting agents were used.

New EGFR inhibitor series of fifteen 5-chloro-3-hydroxymethyl-indole-2-carboxamide derivatives has been designed, synthesized, and tested for antiproliferative activity against a panel of cancer cell lines. The results showed that p-substituted phenethyl derivatives 10, 11, 13, 15 and 17–19 showed superior antiproliferative activity compared to their m-substituted counterparts 12, 14, 16 and 20. Compounds 15, 16, 19 and 20 displayed promising EGFR inhibitory activity as well as an increase in caspase 3 levels. Compounds 15 and 19 increased caspase-8 and 9 levels, as well as inducing Bax and decreasing Bcl-2 protein levels. Compound 19 demonstrated cell cycle arrest at pre-G1 and G2/M phases. The results of the docking study into the active site of EGFR revealed strong fitting of the new compounds with higher binding affinities compared to erlotinib.

We synthesized new N-phenylethyl-1H-indole-2-carboxamides as the first SAR study of allosteric modulators of the CB1 receptor. The presence of the carboxamide functionality was required in order to obtain a stimulatory effect. The maximum stimulatory activity on CB1 was exerted by carboxamides 13 (EC50 = 50 nM) and 21 (EC50 = 90 nM) bearing a dimethylamino or piperidinyl group, respectively, at position 4 of the phenethyl moiety and a chlorine atom at position 5 of the indole.

A series of cis-1,2-diaminocyclohexane derivatives were synthesized with the aim of optimizing previously disclosed factor Xa (fXa) inhibitors. The exploration of 5-6 fused rings as alternative S1 moieties resulted in two compounds which demonstrated improved solubility and reduced food effect compared to the clinical candidate, compound A. Herein, we describe the synthesis and structure-activity relationship (SAR), together with the physicochemical properties and pharmacokinetic (PK) profiles of some prospective compounds.

Condensation of aryl hydrazines with ethyl pyruvate gave the respective hydrazones 4-6; Fischer indolization led to substituted-1H-indole-2-carboxylic acid ethyl esters 7-9. The Mannich reaction of these compounds with formaldehyde and morpholine yielded ethyl 3-(morpholinomethyl)-substituted-1H-indole-2- carboxylates 10-12. The 5,7-dichloro-1H-indole-2-carbohydrazide 13 was cyclized with methyl orthoformate in DMF to give 6,8-dichloro[1,2,4]triazino[4,5-a]indol- 1(2H)-one 14. Vilsmeier-Haack formylation of 7-9 gave ethyl 3-formyl- substituted-1H-indole-2-carboxylates 15-17 whose 2,2′-((5-chloro-2- (ethoxycarbonyl)-1H-indol-3-yl)methylene)bis-(sulfanediyl) diacetic acid 18 was prepared. The reaction of 15 and 16 with substituted anilines by conventional and microwave methods gave ethyl 3-(N-aryliminomethyl)-5-halo-1H-indole-2- carboxylates 19-29. In a cyclocondensation reaction of 19-25 with thiolactic acid or thioglycolic acid substituted indolylthiazolidinones 30-33 were prepared. Reaction of hydrazine hydrate with 15-17 did not give the respective hydrazones but directly led to the cyclized products substituted-3H- pyridazino[4,5-b]indol-4(5H)-ones 34-36, while a reaction with 2,4-dichlorophenylhydrazine yielded the uncyclized hydrazones. The chlorination of 35 and 36 with POCl3 gave pyridazino[ 4,5-b]indoles 39 and 40, respectively; reaction of the latter compounds with morpholine gave 4-(substituted-5H-pyridazino[4,5-b]indol-4-yl)morpholine 41 and 42. Mannich reaction of 34 with formaldehyde and N-ethylpiperazine gave 8-chloro-3-((4- ethylpiperazin-1-yl)methyl)-3H-pyridazino[ 4,5-b]indol-4(5H)-one 43. The microwave assistance of selected reactions has a profound effect on the reaction speed. The structures of the new compounds were confirmed by both analytical and spectral data. Some compounds were subjected to investigations concerning their antimicrobial, tranquilizing, and anticonvulsant activities.
