Rac-7-[(2E)-But-2-eno-yl]-13-chloro-N-cyclo-hexyl-7,8-dihydro-5H-isochromeno[4,3-c]phenanthridine-8-carboxamide.

ABSTRACT: In the title compound, C(31)H(29)ClN(2)O(3), the two heterocyclic rings, belonging to a system of five condensed rings, adopt conformations intermediate between twist-boat and sofa. The secondary amide group is involved in a weak intramolecular N-H?N hydrogen bond. In the crystal, molecules are linked by pairs of C-H?Cl hydrogen bonds to form inversion dimers. These dimers are linked via a C-H?O interaction to form chains propagating along the b-axis direction.

In the title compound, C(31)H(29)ClN(2)O(3), the two heterocyclic rings, belonging to a system of five condensed rings, adopt conformations intermediate between twist-boat and sofa. The secondary amide group is involved in a weak intramolecular N-H⋯N hydrogen bond. In the crystal, molecules are linked by pairs of C-H⋯Cl hydrogen bonds to form inversion dimers. These dimers are linked via a C-H⋯O interaction to form chains propagating along the b-axis direction. ...[more]

Synthesis and Structure-Activity Relationships of 4-Morpholino-7,8-Dihydro-5H-Thiopyrano[4,3-d]pyrimidine Derivatives Bearing Pyrazoline Scaffold.

Project description:Phosphatidylinositol 3-kinase/Protein kinase B/Mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway is abnormally active in the growth and proliferation of cancer cells. The inhibition of PI3K kinase can effectively block the conduction of signaling pathways and is an ideal target for drug design. In this paper; two series of 4-morpholino-7,8-dihydro-5H-thiopyrano[4,3-d]pyrimidine derivatives bearing pyrazoline moiety (7a-l; 8a-l) were synthesized; and their cytotoxicity in vitro were evaluated by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method against four human cancer cell lines including A549; PC-3; MCF-7; and HepG2 cell lines. The activity of the most promising compound 8d against PI3K? kinase was further evaluated. The results indicated that most of the target compounds showed moderate to excellent cytotoxicity and the most promising compound 8d showed excellent cytotoxicity against four cancer cell lines with half maximal inhibitory concentration (IC50) values of 6.02-10.27 ?M. In addition; the compound 8d was found to have a moderate inhibitory activity in the PI3K? enzyme assay. What's more; the compounds of which the substituents of benzene ring at the C-4 position are electron-withdrawing groups such as substituents (Cl; F; Br) have better activity than the compounds containing the electron donating groups (OCH?; H). However; the exact action mechanism is not quite clear right now. Further study will be carried out to identify the exact target in near future.

Synthesis and Biological Evaluation of Novel 4-Morpholino-7,8-dihydro-5H-thiopyrano[4,3-d]pyrimidine Derivatives Bearing Phenylpyridine/ Phenylpyrimidine-Carboxamides.

Project description:Four series of novel 4-morpholino-7,8-dihydro-5H-thiopyrano[4,3-d]pyrimidine derivatives 11a-j, 12a-j, 13a-g and 14a-g bearing phenylpyridine/phenylpyrimidine- carboxamide scaffolds were designed, synthesized and their IC50 values against three cancer cell lines (A549, PC-3 and MCF-7) were evaluated. Eleven of the compounds showed moderate cytotoxicity activity against the cancer cell lines. Structure-activity relationships (SARs) and pharmacological results indicated that the introduction of phenylpyridine-carboxamide scaffold was beneficial for the activity. What's more, the oxidation of the sulfur atom in thiopyran and various types of substituents on the aryl group have different impacts on different series of compounds. Furthermore, the positions of aryl group substituents have a slight impact on the activity of the phenylpyridine-carboxamide series compounds.

Three dimensional quantitative structure-activity relationship of 5H-Pyrido[4,3-b]indol-4-carboxamide JAK2 inhibitors.

Project description:Janus kinase 2 (JAK2) is an intracellular nonreceptor tyrosine kinase that belongs to the JAK family of kinases, which play an important role in survival, proliferation, and differentiation of a variety of cells. JAK2 inhibitors are potential drugs for the treatment of myeloproliferative neoplasms. The three dimensional quantitative structure-activity relationships have been studied on a series of JAK2 inhibitors by comparative molecular field analysis (CoMFA), and comparative molecular similarity indices analysis (CoMSIA). The CoMFA model had a cross-validated coefficient q2 of 0.633, and the relation non-cross-validated coefficient r2 of 0.976. The F value is 225.030. The contributions of steric and electrostatic fields to the activity are 55.2% and 44.8%, respectively. For the CoMSIA study, the q2, r2, and F values of the model are 0.614, 0.929, and 88.771, respectively. The contributions of steric, electrostatic, hydrophobic, hydrogen bond donor, and hydrogen bond donor fields to the activity are 27.3%, 23.9%, 16.4%, 21.7%, and 10.7%, respectively. The CoMFA and CoMSIA models showed strong predictive ability, and the 3D contour plots give the basis on the structure modification of JAK2 inhibitors.

2-Bromo-methyl-N-isopropyl-7,8-dimeth-oxy-1,2-dihydro-1,3-oxazolo[3,2-a]quinoline-4-carboxamide.

Project description:In the title compound, C(18)H(21)BrN(2)O(5), conjugation between the ?-donating N-C-O fragment and the ?-withdrawing carbonyl group results in considerable redistribution of the electron density within the dihydropyridinol ring. This effect is also promoted by the formation of an intra-molecular N-H?O hydrogen bond. The five-membered heterocycle is disordered over two envelope conformations in a 0.35:0.65 ratio.

An efficient three component one-pot synthesis of 5-amino-7-aryl-7,8-dihydro-[1,2,4] triazolo[4,3-a]-pyrimidine-6-carbonitriles.

Project description:A series of novel 5-amino-7-aryl-7,8-dihydro-[1,2,4] triazolo[4,3-a]-pyrimidine-6-carbonitriles were synthesized by a one-pot reaction of 3-amino-1,2,4-triazole, malononitrile and aryl aldehydes in the presence of 20 mol% NaOH in ethanol under heating or ultrasonic irradiation. The structures of the target compounds were confirmed by inspection of their (1)H- NMR, (13)C-NMR, IR and MS spectra. The advantages of this method are short reaction times, good yields, high selectivity and operational simplicity.
