An Efficient Sonochemical Synthesis of Novel Schiff’s Bases, Thiazolidine, and Pyrazolidine Incorporating 1,8-Naphthyridine Moiety and Their Cytotoxic Activity against HePG2 Cell Lines

Novel Schiff ‘s bases 4a-e, 5a, 5b, and 6, thiazolidine 7a-d, and pyrazolidine 8 have been synthesized using the versatile synthon 4-hydroxy-2,7-dimethyl- 1,8-naphthyridine 1. Reactions carried out under ultrasound irradiation showed higher rates and yields than those done under silent conditions. The newly synthesized compounds were evaluated for HepG2 cell growth inhibition. The results obtained revealed that the tested compounds possess inhibitory effect on the growth of HepG2 liver cancer cells. The results were compared to doxorubicin as a reference drug (IC50: 0.04). Compounds 4a and 7b showed the highest inhibition activity against the HepG2 cell line (IC50: 0.047 and 0.041.mu M, resp.) among all the tested compounds.

Tacrines for Alzheimer’s disease therapy. III. The PyridoTacrines

Tacrine was the first drug approved for the treatment of Alzheimer’s disease (AD) in 1993, which was withdrawn in 2013 due to its hepatotoxicity. However, new, non-hepatotoxic tacrine derivatives have been constantly searched for. In this context, since 1997, we have prepared a number of diversely functionalized tacrines by changing the benzene ring present in tacrine to five- or six-membered aromatic ring cores that could present anticholinesterasic activity and additional pharmacological properties. The new compounds were designed as juxtaposed structures between tacrine and the well-known Ca2+ antagonists 1,4-dihydropyridines, with the goal of obtaining multi-target directed ligands for AD. In this account, we present our results on the PyridoTacrine (PyrTac) family of tacrine analogues, resulting from the substitution of the benzene ring by a pyridine. We highlight their pharmacological profile and review similar analogues in the literature. A first set of PyrTac showed inhibitory activity of cholines-terases (ChE) and a blocking profile of voltage-gated Ca2+ channels (VGCC). A second family with improved ChE inhibition lost VGCC blocking activity. However, the lead compound of this family (5f) presented an activating profile of the phosphatase 2A (PP2A) and showed interesting outcomes in experimental in vivo models of AD and stroke. We have identified the PyrTac ethyl 5-amino-2-methyl-6,7,8,9-tetrahydrobenzo[b] [1,8]naphthyridine-3-carboxylate (5f), which presents additional pharmacological properties beyond the mere cholinergic improvement. These new properties warrant attention to 5f and its further development as a new potential therapeutic agent for AD therapy. (C) 2019 Elsevier Masson SAS. All rights reserved.

Exploring the Role of Water Molecules for Docking and Receptor Guided 3D-QSAR Analysis of Naphthyridine Derivatives as Spleen Tyrosine Kinase (Syk) Inhibitors

In the present study, 3D-QSAR analysis was performed utilizing docking based alignment of [1,6]-naphthyridine derivatives as Syk enzyme inhibitors. The role of the water molecules was explored for the docking based alignment that revealed two conserved water molecules important for proper orientation and alignment of naphthyridine inhibitors in the active site of Syk enzyme. The QSAR model was selected having highest value of Q(2) (0.624) and Pearson-r (0.862). The selected model also displayed the highest values of R-2 (0.978) and F-value (184.5) and the lowest SD (0.862). The contour plots developed on the basis of the best model helped to reveal the essential structural features of naphthyridines derivatives responsible for inhibition of Syk enzyme. The generated model and information revealed from it was utilized to design and predict new congeneric molecules that can be used as potential therapeutic agents.
