With the aid of Density Functional Theory (DFT), we designed 1,8-naphthyridine-2,7-diamine as a recognition molecule to read DNA base pairs for genomic sequencing by electron tunneling. NMR studies show that it can form stable triplets with both A:T and G:C base pairs through hydrogen bonding. Our results suggest that the naphthyridine molecule should be able to function as a universal base pair reader in a tunneling gap, generating distinguishable signatures under electrical bias for each of DNA base pairs.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, spectroscopic, and theoretical assessments of solvent structures and their interactions with reaction intermediates. 89343-06-6, Name is Ethynyltriisopropylsilane, SMILES is CC([Si](C(C)C)(C#C)C(C)C)C, belongs to naphthyridine compound.

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.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 89343-06-6. Quality Control of Ethynyltriisopropylsilane.

A triplex-forming oligonucleotide (TFO) can recognize the homopurine-homopyrimidine sequence in DNA duplexes and inhibit the transcription of targeted mRNAs. Recently, we reported that N-acetyl-2,7-diamino-1,8-naphthyridine (N-DA(ac)), incorporated into a TFO, has high binding ability and base recognition selectivity for the pyrimidine bases in the purine-rich chain of the DNA duplex at pH 7.4. However, it was found in this study that the difference in the T-m values between the pyrimidine bases and purine bases decreased by more than 4 degrees C at pH 6.0-7.0. To improve the low base recognition selectivity of the TFO, we designed a new artificial base, (DA)Q(ac), with a quinoline skeleton. The T-m values of the triplexes containing (DA)Q(ac):T-A or (DA)Q(ac):C-G were more than 13 degrees C higher than those of the triplexes containing (DA)Q(ac):A-T or (DA)Q(ac):G-C at pH 7.4. We also observed that under more acidic conditions (pH 6.0-7.0), the base recognition selectivity of DAQac in a triplex was higher than that of N-DA(ac), although the binding ability of (DA)Q(ac) in a triplex was similar to that of N-DA(ac). Additionally, we found that (DA)Q(ac), incorporated into the TFO, could accurately recognize the C-Me-G base pair in the hairpin DNA, similar to the C-G base pair.

Molecular structure of a naphthyridine and pyrazine amine ligand, N-2,N-7-di (pyrazin-2-yl)-1,8-naphthyri-dine-2,7-diamine (H(2)dpznda 1) was studied, and a three-dimensional supramolecular network with a double helix chain structure through intermolecular hydrogen bonds and p-p interactions between the naphthyridine and pyrazine rings was depicted.

The unique occurrence of G-quadruplexes in the AT-rich genome of human malaria parasite Plasmodium falciparum provides hints about their critical roles in parasite survival, pathogenesis, and host immune evasion. An intriguing question is whether these noncanonical structures can serve as molecular targets for small molecule-based interventions against malaria. In this study, we have investigated the pharmacological targeting of G-quadruplexes for parasite inhibition. We observed that bisquinolinium derivatives of 1,8-naphthyridine and pyridine affected the stability and molecular recognition properties of G-quadruplexes in telomeric and subtelomeric regions in P. falciparum. Parasite inhibition and cytotoxicity assays revealed that these ligands effectively inhibit parasite growth with minimal toxic effects in human cells. G-quadruplex interacting ligands caused degeneration and shortening of parasite telomeres. Ligand-induced perturbations in telomere homeostasis also affected transcriptional state of the subtelomeric region harboring antigenic variation genes. Taken together, our results suggest that quadruplex ligand interaction disturbs telomeric/subtelomeric chromatin organization and induces DNA damage that consequently leads to parasite death. Our findings also draw attention to the striking differences in telomere dynamics in the protozoan parasite and human host that can be exploited for selective targeting of the telomeric quadruplex of the parasite as a potential antimalarial strategy.

A new macrocyclic receptor 1 having [1,8]-naphthyridine fluorophore is designed and synthesized for selective fluorescence sensing of Cd2+. Receptor 1 selectively responds to Cd2+ over other tested metal ions via a large enhancement of emission intensity due to the cation-induced CHEF (chelation enhanced fluorescence) effect. Receptor 1 although exhibits some affinity towards Zn2+, it selectively binds Cd2+ over Zn2+. Binding and selectivity were examined by H-1-NMR, fluorescence, UV-vis, mass and IR-spectroscopic techniques. (C) 2011 Elsevier By. All rights reserved.
