Piperidine (I) (1 mole) added to a α,β-dibromoalkanoic acid ester extracts 1 mole HBr. In the cinnamic acid series, hydrolysis of PhCHBrCHBrCO2Me gives 2 α-Br isomers, the allo and the ordinary. The best exptl. argument in favor of the α,β-substitution of the α,β-dipiperidino-2-alkenoic acid ester (II) is the formation, in the cinnamic acid series, of 2 distinct isomeric dipiperidino esters, m. 77° and 127°. In the MeCH:CHCO2H hydrolysis of the MeCHBrCHBrCO2Et gives 2 isomers, iso and ordinary. I (3 moles) added to MeCH:CBrCO2Et gives II. Et α-bromocrotonate, b16 81-2°, and Et α-bromoisocrotonate, b19 80-1°, are obtained by the direct esterification of α-bromocrotonic and α-isocrotonic acids, resp. The action of 3 moles I on each of these 2 isomers produces the dipiperidino compounds, which on hydrolysis with 2N H2SO4 yield MeCH2COCO2H, 2 moles piperidine, and a primary alc. This, and an accessory reaction, in which the hydrolytic products formed are free piperidine the aldehyde RCHO (BzH or AcH) and piperidinoacetic acid, can be, considered as supplementary proof of the α,β structure of the diamine derivatives

The pKa values of 5 [cyclo-(CH2)5N+]Me(CH2)nCO2- (N-methylpiperidinium betaines) and 5 [cyclo-(CH2)5N](CH2)nCO2H were determined by potentiometric titration of their hydrohalides with KOH. Semiempirical geometry optimizations were performed for gaseous betaines. Four conformers were characterized and their PA values estimated The PA values fulfilled the linear correlation with the aqueous pKa values estimated by P. Barczynski et al. (1998). A linear correlation between the calculated heat of formation (ΔHf) and the sum of the N…O1 and N…O2 distances, for the conformers containing the same number of CH2 groups, indicates that they are stabilized by the intramol. electrostatic interactions between the pos. charged nitrogen atom and oxygen atoms of the carboxylate group.

Computed Properties of C7H13NO2. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 1-Piperidineacetic Acid, is researched, Molecular C7H13NO2, CAS is 3235-67-4, about Development of a series of bis-triazoles as G-quadruplex ligands.

Maintenance of telomeres – specialized complexes that protect the ends of chromosomes – is provided by the enzyme complex telomerase, which is a key factor that is activated in more than 80% of cancer cells, but absent in most normal cells. Targeting telomere maintenance mechanisms could potentially halt tumor growth across a broad spectrum of cancer types. Telomeric ends of chromosomes consist of noncoding repeat sequences of guanine-rich DNA. These G-rich ends can fold into structures called G-quadruplexes. Stabilization of G-quadruplexes by small binding mols. called G4 ligands can prevent telomerase enzyme from maintaining telomere integrity in cancer cells. G-quadruplexes can exist in other parts of the genome too, especially within promoter sequences of oncogenes, and also be interesting drug targets. Here, we describe the development of a new series of novel bis-triazoles, designed to stabilize G-quadruplex structures selectively as G4 ligands. FRET assays showed two compounds to be moderately effective G4 binders, with particular affinity for the quadruplex formed by the Hsp90a promoter sequence, and good selectivity for G-quadruplex DNA vs. duplex DNA. However, CD spectroscopy failed to provide any information about the folding topol. of the human telomeric G-quadruplex resulting from its interaction with one of the ligands. All the new ligands showed potent cell growth inhibitory properties against human colon and pancreatic cancer cell lines, as evidenced by the MTT assay; notably, they were more potent against cancer cells than in fetal lung fibroblasts. Docking studies were performed to rationalize the affinity of these ligands for binding to the telomeric parallel G-quadruplex DNA.

The oxidative cleavage of 1,2-diols is a fundamental organic transformation. The stoichiometric oxidants that are still predominantly used for such oxidative cleavage, such as H5IO6 , Pb(OAc)4 , and KMnO4 , generate stoichiometric hazardous waste. Herein, is described a widely applicable and highly selective silver(I)-catalyzed oxidative cleavage of 1,2-diols that consumes atm. oxygen as the sole oxidant, thus serving as a potentially greener alternative to the classical transformations.
