Conformations, structure, vibrations, chemical shift and reactivity properties of isoquinoline-1-carboxylic acid and isoquinoline-3-carboxylic acid – Comparative investigations by experimental and theoretical techniques

The most stable conformer of isoquinoline-l-carboxylic acid (IQ1CA) and isoquinoline-3-carboxylic acid (IQ3CA) are determined and the geometry has been optimised with B3LYP method using high level 6 -311++G** and cc-pVTZ basis sets. The structure, electronic properties, vibrational fundamental modes, thermodynamic properties and chemical shifts of the compounds are investigated. The vibrational fundamental modes are assigned and analysed by utilising FT-IR and FT-Raman spectrum of the compounds recorded in the range of 4000-400 and 4000-100 cm(-1), respectively. The LUMO-HOMO energy difference is determined to explain the charge transfer within the molecule. The molecular electrostatic potential and total electron density of the molecules are determined to explain the size, shape and the reactive sites (polar) of the molecules. The H-1 and C-13 NMR chemical shifts of the compounds are determined by Gauge Invariant Atomic Orbital (GLAD) method using DMSO-d 6 solvent by B3LYP/cc-pVTZ method. The local and global chemical reactivity properties of the compounds have been investigated with the help of global and local reactivity descriptors. (C) 2020 Elsevier B.V. All rights reserved.

Inhibition of complex I by isoquinoline derivatives structurally related to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)

Mitochondrial respiratory failure secondary to complex I inhibition may contribute to the neurodegenerative process underlying nigral cell death in Parkinson’s disease (PD). Isoquinoline derivatives structurally related to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) or 1-methyl-4-phenylpyridinium (MPP(+)) may be inhibitors of complex I, and have been implicated in the cause of PD as endogenous neurotoxins. To determine the potency and structural requirements of isoquinoline derivatives to inhibit mitochondrial function, we examined the effects of 22 neutral and quaternary compounds from three classes of isoquinoline derivatives (11 isoquinolines, 2 dihydroisoquinolines, and 9 1,2,3,4-tetrahydroisoquinolines) and MPP(+) on the enzymes of the respiratory chain in mitochondrial fragments from rat forebrain. With the exception of norsalsolinol and N,n-propylisoquinolinium, all compounds inhibited complex I in a time-independent, but concentration-dependent manner, with IC(50)s ranging from 0.36-22 mM. Several isoquinoline derivatives were more potent inhibitors of complex I than 1-methyl-4-phenylpyridinium ion (MPP(+)) (IC50 = 4.1 mM), the most active being N-methyl-6-methoxy-1,2,3,4-tetrahydroisoquinoline (IC50 = 0.36 mM) and 6-methoxy-1,2,3,4-tetrahydroisoquinoline (IC50 = 0.38 mM). 1,2,3,4-Tetrahydroisoquinoline was the least potent complex I inhibitor (IC50 approximate to 22 mM). At 10 mM, only isoquinoline (23.1%), 6,7-dimethoxyisoquinoline (89.6%), and N-methylsalsolinol (34.8%) inhibited (P < 0.05) complex II-III, but none of the isoquinoline derivatives inhibited complex IV. There were no clear structure-activity relationships among the three classes of isoquinoline derivatives studied, but lipophilicity appears to be important for complex I inhibition. The effects of isoquinoline derivatives on mitochondrial function are similar to those of MPTP/MPP(+), so respiratory inhibition may underlie their reported neurotoxicity. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 36476-78-5. The above is the message from the blog manager. Name: Azetidine-3-carboxylic acid.
