Selective synthesis and photoluminescence study of pyrazolopyridopyridazine diones and N-aminopyrazolopyrrolopyridine diones

The newly designed luminol structures of pyrazolopyridopyridazine diones and N-aminopyrazolopyrrolopyridine diones were synthesized from versatile 1,3-diaryfuropyrazolopyridine -6,8-diones, 1,3-diarylpyrazolopyrrolopyridine-6,8-diones, or 1,3-diaryl-7- methylpyrazolopyrrolopyridine -6,8-diones with hydrazine monohydrate. Photoluminescent and solvatofluorism properties containing UV-Vis absorption, emission spectra, and quantum yield (Phif) study of pyrazolopyridopyridazine diones and N-aminopyrazolopyrrolopyridine diones were also studied. Generally, most of pyrazolopyrrolopyridine-6, 8-diones 6 exhibited the significant fluorescence intensity and the substituent effect when compared with N-aminopyrazolopyrrolopyridine diones, particularly for 6c and 6j with a m-chloro group. Additionally, the fluorescence intensity of 6j was significantly promoted due to the suitable conjugation conformation. Based on the quantum yield (Phif) study, the value of compound 6j (0.140) with planar structural skeletal was similar to that of standard luminol (1, 0.175).

N,N-coupled heterobicycles from cyclic hydrazine derivatives. Part 8: Synthesis of 3-imino substituted 1-thioxo-2,3,5,10-tetrahydro-[1,2,4]triazolo[1,2-b]phthalazines and 1-thioxo-5,10-dihydro-[1,3,4]thiadiazolo[3,4-b]phthalazines

The preparation of the mostly 3-arylimino substituted derivatives 4 of the hitherto unknown [1,3,4]thiadiazolo[3,4-b]phthalazine ring system succeeded by treatment of the related 2-thiocarbamoyl-1,2,3,4-tetrahydrophthalazines 2 with thiophosgene under mild conditions. The reaction of the 2 with arylisothiocyanates under heating yields the 2-aryl-1-thioxo-3-arylimino[1,2,4]triazolo[1,2-b]phthalazines 5.

Short-lived excited triplet states studied by time-resolved EPR spectroscopy

In this review, we present an overview of the application of time-resolved electron paramagnetic resonance (TREPR) to the study of excited triplet states. After a brief discussion of background and experimental methods, triplet properties clarified by TREPR are reviewed to show how TREPR provides rich information about electronic and molecular structures and dynamic properties of the lowest excited triplet states. The review includes discussion of the properties of non-phosphorescent triplet states, various interactions (configurational, vibronic and spin-orbit) and triplet properties, molecular distortions, and triplet states related to excited-state proton transfer. For each topic, typical examples are taken mainly from work carried out in the authors’ laboratories in Kyoto and Sendai over the last two decades. Finally, recent new advances are reviewed briefly by focusing attention on two topics: excited triplet states in liquid solution and multiplet excited states generated by triplet-radical interactions.

New preclinical development of a c-met inhibitor and its combined anti-tumor effect in c-met-amplified NSCLC

c-Met is a receptor tyrosine kinase with no commercially available product despite being a pivotal target in cancer progression. Unlike other c-Met inhibitors that fail clinically, ABN401 is a newly synthesized c-Met inhibitor that is not potentially degraded by aldehyde oxidase (AO) in human liver cytosol. This study aimed to determine the physicochemical stability, pharmacokinetics in beagle dogs, and therapeutic effect of ABN401 in a c-Met-amplified non-small-cell lung cancer (NSCLC) patient-derived xenograft (PDX) model. ABN401 was found to be a weak basic compound, with pKa and log P values of 7.49 and 2.46, respectively. It is poorly water-soluble but soluble at acidic pH. The accelerated storage stability is dependent on temperature, but the purity remains at over 97% after 6 months. The bioavailability is approximately 30% in dogs and it is highly efficient in the PDX model, achieving around 90% tumor growth inhibition in combination with erlotinib. These observations indicate that the compound is acceptable for the next phase of trials.

Stabilizers of edaravone aqueous solution and their action mechanisms. 1. Sodium bisulfate

Edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one) has been used as a free radical scavenging drug for the treatment of acute ischemic stroke in Japan since 2001. Edaravone is given to patients intravenously; therefore, it is distributed in the form of an aqueous solution. However, aqueous solutions of edaravone are very unstable because it is present as edaravone anion, which is capable of transferring an electron to free radicals including oxygen, and becomes edaravone radical. We observed the formation of hydrogen peroxide and edaravone trimer when aqueous edaravone solution was kept at 60 C for 4 weeks. We proposed the mechanism of edaravone trimer formation from edaravone radicals. Lowering the pH and deoxygenation can effectively increase the stability of aqueous edaravone solution, since the former reduces edaravone anion concentration and the latter inhibits edaravone radical formation. Addition of sodium bisulfite partially stabilized aqueous edaravone solutions and partially inhibited the formation of edaravone trimer. Formation of bisulfite adduct was suggested by 13C NMR and HPLC studies. Therefore, the stabilizing effect of sodium bisulfite is ascribed to the formation of a bisulfite adduct of edaravone and, consequently, reduction in the concentration of edaravone anion.
