Antifungal activity of β-carbolines on Penicillium digitatum and Botrytis cinerea
(Academic Press Ltd - Elsevier Science Ltd, 2017-04)
β-carbolines (βCs) are alkaloids widely distributed in nature that have demonstrated antimicrobial properties. Here, we tested in vitro six βCs against Penicillium digitatum and Botrytis cinerea, causal agents of postharvest ...
Experimental and computational study of solvent effects on one- and two-photon absorption spectra of chlorinated harmines
(Royal Society of Chemistry, 2015-04)
A combined experimental and computational study of solvent effects on one- and two-photon absorption spectra of three chlorinated harmine derivatives is presented. The systems studied were protonated forms of 6-chloroharmine, ...
Determining the molecular basis for the pH-dependent interaction between 2′-deoxynucleotides and 9H-pyrido[3,4-b]indole in its ground and electronic excited states
(Royal Society of Chemistry, 2014-06)
Interaction between norharmane and three different 20 -deoxynucleotides (dNMP) (20 -deoxyguanosine 50 -monophosphate (dGMP), 20 -deoxyadenosine 50 -monophosphate (dAMP) and 20 -deoxycytidine 50 -monophosphate (dCMP)), in ...
Photophysical properties of a β-Carboline Rhenium (I) complex. Solvent effects on excited states and their redox reactivity
(Elsevier, 2021-12)
The photochemical and photophysical properties of a Re(I) tricarbonyl complex, ClRe(CO)3(nHo)2, where nHo = 9H-pyrido[3,4-b] indole (norharmane), were investigated in solution phase by a combination of steady state emission ...
Light-induced full aromatization and hydroxylation of 7-methoxy-1-methyl-3,4-dihydro-2H-pyrido[3,4-b]indole alkaloid: Oxygen partial pressure as a key modulator of the photoproducts distribution
(Elsevier Science SA, 2019-10)
Full-aromatic and partially hydrogenated β-carboline (βC) derivatives constitute a group of alkaloids widely distributed in a great variety of living systems. In plants and bacteria, tetrahydro-βCs are the primary product ...
Current landscape of the spectroscopic and photochemical properties of β-carboline alkaloids in aqueous media towards understanding their biological role: Review
(Asociación de Química Argentina, 2020-12)
Las β-carbolinas (βCs) constituyen una familia de alcaloides estructuralmente relacionados con el 9Hpyrido[3,4-b]indol o norharmano. Estos alcaloides están presentes en una amplia gama de organismos vivos, filogenéticamente ...
Actividad antiviral de alcaloides naturales y sintéticos frente a los virus dengue y ZikaAntiviral activity of natural and synthetic alkaloids against dengue and Zika viruses
(2018-03-20)
Los virus dengue (DENV) y Zika (ZIKV), pertenecientes al género Flavivirus dentro de la familia Flaviviridae, son importantes patógenos para el hombre para los cuales no se dispone aún de un tratamiento antiviral específico. ...
Mastering tricyclic ring systems for desirable functional cannabinoid activity
(Elsevier Masson, 2013-11)
There is growing interest in using cannabinoid receptor 2 (CB2) agonists for the treatment of neuropathic pain and other indications. In continuation of our ongoing program aiming for the development of new small molecule ...
