A RhCp* (Cp* = pentamethylcyclopentadienyl) complex bearing an NAD(+)/NADH-functionalized ligand, [RhCp*(pbn)Cl]Cl ([1] Cl, pbn = (2-(2-pyridyl) benzo[b]-1,5-naphthyridine)), was synthesized. The cyclic voltammogram of [1]Cl in CH3CN shows two reversible redox waves at E-1/2 = -0.58 and -1.53 V (vs. the saturated calomel electrode (SCE)), which correspond to the Rh-III/Rh-I and pbn/pbn(center dot-) redox couples, respectively. The addition of acetic acid to the solution afforded the proton-coupled two-electron reduction of [1]Cl at -0.62 V, from which [RhCp*(pbnHH)Cl](+) was selectively generated, probably via a hydride transfer from a Rh-III-hydride intermediate to the pbn ligand. Complex [1]Cl is stable under acidic conditions, whereas a methyl proton of the Cp* moiety dissociates under basic conditions. The resulting anionic methylene group attacks the para carbon of the free pyridine of pbn, accompanied by protonation of the nitrogen atom of the ligand. As a result, treatment of [1]Cl with a base produces selectively the cyclic complex [1CH]Cl, which bears a reduced pbn framework (pbnCH). [1CH]Cl forms 1 : 1 adducts with PhCOO-via hydrogen bonding. A similar adduct, formed by a Ru-pbnHH scaffold and RCOO-(R = CH3, C6H5), has been reported to react with CO2 to produce HCOO-under concomitant regeneration of Ru-pbn. The adduct of [1CH]Cl with PhCOO-, however, lacks such hydride-donor ability, due to a steric barrier in the molecular structure of [1CH]Cl, which hampers the hydride transfer.

A highly efficient and simple procedure has been developed for the synthesis of 9-(3-fluoro-4-methoxyphenyl)-6-aryl-[1,2,4]triazolo[4,3-a][1,8] naphthyridines by ionic liquid Cu(II) oxidative cyclization of 2-(2-(3-fluoro-4-methoxybenzylidene)hydrazinyl)-3-phenyl-1,8-naphthyridine under microwave irradiation. Synthesized compounds have been described by microanalysis, infrared, H-1 NMR spectroscopy, and mass spectrometry. Sixteen of the synthesized compounds were evaluated for their antimicrobial activity against bacteria, such as Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Klebsiella pneumoniae, as well as fungi, such as Aspergillus flavus and Fusarium oxysporum. Results of the antimicrobial screening showed that the compounds 3b, 3g, and 3j have maximal zones of inhibition against the tested bacterial strains. Docking studies were carried out for the three most active compounds 3b, 3g, and 3j along with the inactive compound 3a.

Currently, a search for selective antagonists of luteinizing hormone (LH) receptor, which are necessary to suppress steroidogenesis in hormone-dependent tumors and to prevent the ovarian hyperstimulation syndrome, is carried out. One approach to solving this problem is the development of low-molecular-weight antagonists of the allosteric site of this receptor located in its transmembrane domain. The aim of this work was to develop the heterocyclic compounds, the derivatives of thieno[2,3-d]pyrimidine (TP31), pyrimido [4,5,6-de] [1,6]naphthyridine (PP10), and pyrido[3,4-d]pyrimidine (PP17), and to study their ability to influence the functional activity of the LH receptor in the in vitro and in vivo conditions. It was shown that at micromolar concentrations TP31 suppressed stimulating effects of human chorionic gonadotropin (hCG) on the adenylyl cyclase activity in rat testicular membranes. Yet more pronounced was the suppressing effect of TP31 on the stimulating effect of TP03, an allosteric agonist of the LH receptor. This was due to a higher selectivity of the TP31 antagonist with respect to the cAMP-dependent signaling cascades, predominantly activated by TP03 and realized through Gs proteins. PP17 inhibited stimulatory effects of hCG and TP03 on the adenylyl cyclase activity to a similar extent but was less potent than TP31. Upon intratesticular (10 mg/kg) or intraperitoneal (45 mg/kg) administration to male rats, TP31 and PP17 decreased the baseline plasma level of testosterone and inhibited the testosterone production stimulated by hCG (100 IU/rat); the inhibitory effect of TP31 was much more pronounced than that of PP17. PP10 exhibited a weaker antagonistic activity than TP31 and PP17 in the in vitro and in vivo conditions. The data obtained indicate that TP31, the most active functional antagonist among the studied compounds, by binding to the allosteric site of the LH receptor, makes it less accessible to allosteric agonists and impairs the hormonal signal transduction through the LH receptor. This suggests the prospects of the development of TP31-based inhibitors of LH-dependent pathways and steroidogenesis.

The human luteinizing hormone receptor (hLH-R) is a member of the glycoprotein hormone family of G-protein-coupled receptors (GPCRs), activated by luteinizing hormone (hLH) and essentially involved in the regulation of sex hormone production. Thus, hLH-R represents a valid target for the treatment of sex hormone dependent cancers and diseases (polycystic ovary syndrome, uterine fibroids, endometriosis) as well as contraception. Screening of the Bayer compound library led to the discovery of tetrahydrothienopyridine derivatives as novel, small molecule (SMOL) hLH-R inhibitors and to the development of BAY-298, the first nanomolar hLH-R antagonist reducing sex hormone levels in vivo. Further optimization of physicochemical, pharmacokinetic, and safety parameters led to the identification of BAY-899 with an improved in vitro profile and proven efficacy in vivo. BAY-298 and BAY-899 serve as valuable tool compounds to study hLH-R signaling in vitro and to interfere with the production of sex hormones in vivo.

Four new Co(III) complexes, namely [Co(ca)(3)](PF6)(3), [Co(phen)(2)(cq)](PF6)(3), [Co(bnp)(3)] (PF6)(3), and [Co(phen)(2)(bnp)](PF6)(3) (where cq = chromeno[2,3-b]quinoline, phen = 1,10-phenanthroline and bnp = dibenzo[b,g][1,8]naphthyridine), were synthesized and structurally characterized. Spectroscopic data suggested an octahedral geometry for all the complexes. Binding studies of these complexes with double-stranded (dc)DNA were analyzed by absorption spectra, viscosity, and thermal denaturation studies. The mulls revealed that the metal complex intercalates into the DNA base stack as intercalator. The oxidative cleavage activities of the complexes were studied with supercoiled pUC19 DNA using gel electrophoresis and the results show that the complexes have potent nuclease activity.

Molecular architectures possessing the combination of heteroaromatic and saturated N-heterocycles are of great importance because of their higher solubility in the gastrointestinal tract due to weak crystal packing in the three-dimensional structure. Other biological activity like selectivity is also increased in a positive way. However, compared to fully aromatic fused heterocycles, synthesis of partially saturated fused heterocycles is much more difficult since the later needs greater control over the reaction conditions. In this context, 1,2,3,4-tetrahydronaphthyridines (THNADs) are essential part of pharmaceutically important natural products and drug molecules. However, the synthesis of THNAD is seldom reported in literature. To the best of our knowledge, this is the first report of metal-free one pot synthesis of 1,2,3,4-tetrahydro-1,6-naphthyridines without starting from any nitrogen heterocycles in water. Moreover, this study discloses the involvement of isocyanide in a chemical reaction whose net effect is only to reduce a C=C bond which is unusual in isocyanide literature.
