The X-ray crystal structure of 2-(4,5-dihydro-5-phenoxymethyl-1,3-oxazol-2-ylamino)-7-(2-hydroxy-3-phenoxypropyl)hexahydro-2H,6H-pyrimido[6,1-b][1,3]oxazin-6-one (1), a structure of adduct formed by the reaction of 5-(phenoxymethyl)-2-amino-2-oxazoline and acrolein, has been established. The present work deals with the structural identification of the adduct 1 and presents a plausible mechanism for its formation. It crystallizes in the monoclinic space group P21/c with cell parameters a = 21.3337 (10) Å, b = 11.3712 (7) Å, c = 10.4936 (7) Å, β = 103.041 (3), V = 2480.0 (3) Å3, Z = 4. C26H32N4O6, Dc = 1.330 g/cm3, μ (Cu Kα) = 1.5418 Å, S = 1.188, F (000) = 1056, R = 0.0501, and wR = 0.1584. La structure complète de la 2-(4,5-dihydro-5-phénoxymethyl-1,3-oxazol-2-ylamino)-7-(2-hydroxy-3-phénoxypropyl)hexahydro-2H,6H-pyrimido[6,1-b][1,3]oxazin-6-one 1, une structure d'adduit formée lors de la réaction de la 5-(phénoxyméthyl)-2-amino-2-oxazoline et de l'acroléine, a été établie sans équivoque par une analyse cristallographique aux rayons X. Le présent travail porte sur l'identification structurale de l'adduit 1 et présente un mécanisme plausible pour sa formation. La molécule cristallise dans le système monoclinique, dans le groupe spatial P21/c avec a = 21.3337 (10) Å, b = 11.3712 (7) Å, c = 10.4936 (7) Å, β = 103.041 (3), V = 2480.0 (3) Å3, Z = 4. C26H32N4O6, Dc = 1.330 g/cm3, μ (Cu Kα) = 1.5418 Å, S = 1.188, F (000) = 1056, R = 0.0501 et wR = 0.1584.

The 1-methyl-3-{4-[(4-(2-oxo-2,3-dihydro-1H-benzimidazol-1-yl)piperidin-1-yl)benzyl]}-2-phenylindole compound has been successfully synthesized via a multistep pathway starting from 2-phenylindole. Structure characterization of this new indole derivative was done by FTIR, 1H-NMR, 13C-NMR, and HRMS spectral analysis. The title compound showed high cytotoxic potential against five leukemia cell lines (K562, HL60, U937, U266, and Jurkat cell lines).

Novel series of bis- and tris-pyrrolo[1,2-a]quinoxaline derivatives 1 were synthesized and tested for in vitro activity upon the intraerythrocytic stage of W2 and 3D7 Plasmodium falciparum strains. Biological results showed good antimalarial activity with IC50 in the μM range. In attempting to investigate the large broad-spectrum antiprotozoal activities of these new derivatives, their properties toward Leishmania donovani were also investigated and revealed their selective antiplasmodial profile. In parallel, the in vitro cytotoxicity of these molecules was assessed on the human HepG2 cell line. Structure-activity relationships of these new synthetic compounds are discussed here. The bis-pyrrolo[1,2-a]quinoxalines 1n and 1p were identified as the most potent antimalarial candidates with selectivity index (SI) of 40.6 on W2 strain, and 39.25 on 3D7 strain, respectively. As the telomeres of the parasite could constitute an attractive target, we investigated the possibility of targeting Plasmodium telomeres by stabilizing the Plasmodium telomeric G-quadruplexes through a FRET melting assay by our new compounds.

The tyrosine-protein kinase Src, also known as proto-oncogene c-Src or simply c-Src, is a non-receptor tyrosine kinase protein that has been shown to be involved in the regulation of important cellular processes including migration, survival and proliferation. In fact, Src activation has been associated with multiple cancers, such as colon, breast, pancreas, lung, or brain (Roskoski, R. Jr. Pharmacol. Res. 2015, 94, 9-25; Creedon, H., et al., Crit. Rev. Oncog. 2012, 17, 145-159). There are only few Src inhibitors in clinical development, therefore, there is an urgent need to identify new low molecular weight therapeutics able to inhibit Src and, thus, to modulate aberrant pathways leading to malignant transformation of cells (Lu, X.L., et al., Curr. Med. Chem. 2012, 19, 1821-1829). Heterocyclic compounds attracted a lot of attention because of their wide spread biological activities. Thus, we have previously reported the synthesis of biological active heterocyclic derivatives based on the reactivity of the amidine moiety of 2-amino-2-oxazolines 2 with bis-electrophiles (Massip, S., et al., Bioorg. Med. Chem. 2006, 14, 2697-2719).

In a preliminary screening testing our heterocycles library, we have identified a “hit” (compound 1d) derived from various substituted 6-formyl-oxazolo[3,2-a]pyrimidines as a new Src kinase inhibitor (IC50 = 4 µM). These original oxazolo[3,2-a]pyrimidine derivatives 1a-k were synthesized through a Diels-Alder cycloaddition of alkylidene derivatives of 2-amino-2-oxazoline (compounds 3a-k) with acrolein, as an electron-poor dienophile, a reaction previously described by our group (Guillon, J., et al., Synlett 2002, 8, 1249-1252). Versatility given by this reaction allowed us to access a promising family of diversely substituted 6-formyl-oxazolo[3,2-a]pyrimidines with inhibitory effect on Src kinase.
