Condensation of 4-(4-methoxyphenyl)tetrahydro-2H-pyran-4-carbonyl chloride I [R1 = Cl] with hydrazine hydrate, furan-2- and 2,5-dimethylfuran-2-carbohydrazides gave disubstituted hydrazides II [R2 = furan-2-carbonyl, (4,5-dimethylfuran-2-carbonyl), 4-(4-methoxyphenyl)tetrahydropyran-4-carbonyl], whose cyclization formed sym. and unsym. 2,5-disubstituted 1,3,4-oxadiazoles III [R3 = 2-furyl, 4,5-dimethyl-2-furyl, 4-(4-methoxyphenyl)tetrahydropyran-4-yl]. Et 4-[4-(4-methoxyphenyl)-tetrahydro-2H-pyran-4-carboxamido]benzoate IV [R4 = CO2Et] was reacted with hydrazine to obtain N-[4-(hydrazinocarbonyl)-phenyl]-4-(4-methoxphenyl)tetrahydro-2H-pyran-4-carboxamide IV [R4 = C(O)NHNH2]. Treatment of IV [R4 = C(O)NHNH2] latter with tri-Et orthoformate gave a monosubstituted 1,3,4-oxadiazole IV [R4 = 1,3,4-oxadiazol-2-yl], and with carbon disulfide, a 5-sulfanyl-1,3,4-oxadiazole derivative IV [R4 = (5-sulfanyl-1,3,4-oxadiazol-2-yl)] was obtained. The subsequent alkylation of this derivative IV [R4 = (5-sulfanyl-1,3,4-oxadiazol-2-yl)] with 5-metoxyfuran-2-Me and benzylaminocarbonylmethyl chlorides substituted chlorides resulted in the synthesis of the corresponding novel S-substituted oxadiazole derivatives V [R5 = 5-methoxycarbonyl-2-furyl, benzylcarbamoyl]. The synthesized compounds I, II, III, IV and V were tested for their antibacterial activity.

M. M.; Youssif, Bahaa G. M.; Brown, Alan B.; Fathy, Hazem M.; Aly, Ashraf A., which mentions a compound: 3326-71-4, SMILESS is O=C(C1=CC=CO1)NN, Molecular C5H6N2O2, HPLC of Formula: 3326-71-4.

Pyrano[3,2-c]quinoline derivatives have been synthesized and utilized to obtain various new hetero-annulated triazolopyrimidine, containing quinoline, pyran, 1,2,4-triazine and pyrimidine in good yields. Newly synthesized compounds have been characterized by spectral data and elemental anal. Most of the synthesized compounds showed moderate to weak antiproliferative activity on most cancer cell lines, especially leukemia and breast cancer cell lines. The open chain formimidic acid Et ester is slightly more potent than hetero-annulated systems. The most active compounds were further investigated for caspase activation, Bax activation and Bcl-2 down regulation compared to doxorubicin as a standard, and indeed exhibited mainly cell cycle arrest at the Pre-G1 and G2/M phases. The transcription effects of 5a and 5b on the p53 were assessed and compared with the reference doxorubicin. The results revealed an increase of 12-19 in p53 level compared to the test cells and that p53 protein level of 5a and 5b was significantly inductive (991, and 639 pg/mL, resp.) in relation to doxorubicin (1263 pg/mL).

A Journal, Hyomen Gijutsu called Evaluation of the anticorrosivity by low-energy photoelectron emission of the magnetic metal particles for magnetic recording media, Author is Watanabe, Haruo; Sato, Fumihiko; Imai, Jun; Mori, Shigeyuki, which mentions a compound: 610-09-3, SMILESS is O=C([C@H]1[C@@H](C(O)=O)CCCC1)O, Molecular C8H12O4, HPLC of Formula: 610-09-3.

The correlation between the anticorrosivity and the intensity of the low-energy photoelectron emission of Fe particles for magnetic recording was studied. Particles with higher anticorrosivity showed lower emission intensity. Particles treated with cis-1,2-cyclohexyldicarboxylic acid showed a higher emission threshold. This higher threshold was explained by the formation of a surface potential barrier on the outer layer of γ-Fe2O3 by anionic species.

Enantiomerically pure C16-alkyl amides derived from cis and trans cycloalkane-1,2-dicarboxylic acids, resp., have been synthesized and their behavior as organogelators has been investigated. These compounds include cis/trans diastereomeric cyclobutane and cyclohexane derivatives with the aim to explore the influence of the ring size as well as the relative configuration in their hierarchical self-assembly to form gels. High resolution 1H NMR spectroscopy studies allowed the determination of the dynamics of the gelation process in [D8]toluene and the sol-gel transition temperature The morphol. and size of the aggregates have been investigated and results have shown that, in the case of cyclobutane derivatives, the cis/trans stereochem. is not relevant for the gelation behavior and the properties of the soft-materials obtained, but it is remarkable for cyclohexane diamides, which are better organogelators. The four compounds produce chiral aggregates despite that two of them are meso achiral mols. We show herein that this fact is an example of stochastic symmetry breaking induced by sonication. The self-assembly of these mols. has been modelled providing information and support about the structure and the chirality of the aggregates.
