Cationic dipyridylamine substituted zinc tetrapyrazinoporphyrazine derivatives for photodynamic therapy

Two kinds of cationic zinc tetrapyrazinoporphyrazine derivatives substituted with ortho- or para- methylpyridinium groups on the peripheral position were synthesized and characterized. The solubility and aggregation behavior of each material were estimated in various solvents, which show different aspect depending on the position of nitrogen on methylpyridinium groups. The fluorescence quantum yield (PhiF) values of both cationic tetrapyrazinoporphyrazines were measured and the singlet oxygen quantum (PhiDelta) yield value were measured by indirect method with DPBF (1,3-diphenylisobenzofuran) in DMSO. Both PhiF and PhiDelta of cationic zinc tetrapyrazinoporphyrazine derivatives exhibited reasonable values for photodynamic therapy application. The cationic zinc tetrapyrazinoporphyrazine derivatives substituted methylpyridinium groups increased solubility in aqueous solvent but also showed the suitable properties as the photosensitizers for photodynamic therapy.

Lewis-base adducts of lead(II) compounds. XV synthesis and structure of some adducts of Bis(2-pyridyl)amine with lead(II) salts

Several complexes of bis(2-pyridyl)amine (‘dpa’) with lead(II) salts have been synthesized and subjected to room-temperature single-crystal X-ray studies. 1:1 Adducts have been obtained with lead(II) bromide and iodide. They have similar unit cells, also similar to those of a variety of other N,N?-heteroaromatic bidentate ligand adducts with metal(II) halides, and the C2/c cell described elsewhere in this series may be regarded as archetypical. [(dpa)PbBr2](?/?) is monoclinic, P 21/a, a 9.791(4), b 9.720(4), c 16.498(4) A, beta 95.96(4), Z = 4 f.u.; conventional R on |F| at convergence was 0.066 for N = 2717 ‘observed’ (I > 3sigma(I)) reflections. [(dpa)PbI2](?/?) is monoclinic. P21/c, a 8.299(2), b 10.229(3), c 16-905(5) A, beta 101.47(2), Z = 4 f.u.; R was 0.044 for N 2140. Both complexes, like their 2,2?-bipyridine and 1,10-phenanthroline analogues, are linear polymers with six-coordinate (cis-N2)Pb(mu-X)4 environments linked in infinite … (mu-X)2Pb(mu-X)2…one-dimensional chains, and with dpa being bidentate. A 2:1 adduct of bis(2-pyridyl)amine with lead(II) acetate (‘Pb(ac)2?) is also described. [(dpa)2Pb(ac)2](?/?) is monoclinic, C 2/c, a 28.835(5), b 10.868(3), c 7.665(2) A, beta 94.21(2), Z = 4; R was 0.029 for N 1854. The complex is a linear polymer along c; the lead atom lies on a crystallographic twofold axis with a coordination environment comprising a pair of symmetry-related dpa ligands, in this case unidentate (Pb-N 3.092(6) A), and a pair of symmetry-related bidentate acetate ligands (Pb-O 2.465(4) and 2.568(5) A) with the first oxygen atom performing an additional bridging function to adjacent symmetry-related lead atoms (Pb-O 2.663(4) A).

Synthesis and SAR of Imidazo[1,5-a[pyridine derivatives as 5-HT4 receptor partial agonists for the treatment of cognitive disorders associated with Alzheimer’s disease

Alzheimer’s disease (AD) is a neurodegenerative disease which has a higher prevalence and incidence in older people. The need for improved AD therapies is unmet. The 5-hydroxytryptamine4 receptor (5-HT4R) partial agonists may be of benefit for both the symptomatic and disease-modifying treatment of cognitive disorders associated with AD. Herein, we report the design, synthesis and SAR of imidazo[1,5-a] pyridine derivatives as 5-HT4R partial agonists. The focused SAR, optimization of ADME properties resulted the discovery of compound 5a as potent, selective, brain penetrant 5-HT4 partial agonist as a lead compound with good ADME properties and efficacy in both symptomatic and disease modifying animal models of cognition.

Enzymic transfer of 6-modified D-galactosyl residues: Synthesis of biantennary penta- and hepta-saccharides having two 6-deoxy-D-galactose residues at the nonreducing end and evaluation of 6-deoxy-D-galactosyl transfer to glycoprotein using bovine beta-(1 4)-galactosyltransferase and UDP-6-deoxy-D-galactose

UDP-6-Deoxy-D-galactose and UDP-6-deoxy-6-fluoro-D-galactose were synthesized and their transfer to 2-acetamido-2-deoxy-D-glucose (N-acetyl-D-glucosamine) by beta-(1 ? 4)-galactosyltransferase was examined. The transfer rates of 6-deoxy-D-galactose and 6-deoxy-6-fluoro-D-galactose were 1.3 and 0.2% of that of D-galactosyl transfer, respectively. The 2-acetamido-4-O-(6-deoxy-beta-D-galactopyranosyl)-2-deoxy-D-glucopyranos e (6′-deoxy-N-acetyllactosamine) and methyl 2-acetamido-4-O-(6-deoxy-6-fluoro-beta-D-galactopyranosyl)-2-deoxy-D-glu copyranoside (6′-deoxy-6′-fluoro-N-acetyllactosamine) were synthesized enzymatically in 30 and 59% yields, respectively. Further, 6-deoxy-D-galactose could be completely transferred to N-linked type biantennary oligosaccharides having two N-acetyl-D-glucosaminyl residues at the nonreducing end to give the corresponding penta- and hepta-saccharides in 55 and 57% yields, respectively. An assay of 6-deoxy-D-galactosyl transfer using asialo agalacto alpha1-acid glycoprotein as an acceptor suggested that 6-deoxy-D-galactose was transferred to about 30% of the N-acetyl-D-glucosaminyl residues in the N-linked oligosaccharides of the glycoprotein.

Discovery of 2,4,6-trisubstitued pyrido[3,4-d]pyrimidine derivatives as new EGFR-TKIs

Targeting acquired drug resistance is the major challenge in the treatment of EGFR-driven non-small cell lung cancer (NSCLC). In this study, a novel class of compounds containing pyrido[3,4-d]pyrimidine scaffold was designed as new generation EGFR-TKIs to overcome this challenge. The most promising compound B30 inhibited HCC827 and H1975 cells growth with the IC50 values of 0.044 muM and 0.40 muM, respectively. Meanwhile, B30 displayed potent inhibitory activity against the EGFRL858R (IC50 = 1.1 nM) and EGFRL858R/T790M/C797S (IC50 = 7.2 nM). B30 could suppress EGFR phosphorylation in a dose-dependent manner in HCC827 cell line and significantly induce the apoptosis of HCC827 cells. Molecular docking indicated that the hydroxyl in B30 could form additional hydrogen bond with mutant Ser797. These findings strongly support our assumption that 2,4,6-trisubstitued pyrido[3,4-d] pyrimidine derivatives can serve as EGFR-TKIs. The predicted hydrogen bond interaction formed by a small molecule inhibitor with mutant Ser797 is available to design the fourth-generation EGFR-TKIs.
