Theoretical Study of the Arachidonic Acid Conversion into Leukotriene A4 Catalyzed by Human 5-Lipoxygenase: Hydroperoxidation and Epoxidation Mechanisms and Arachidonic Acid Active Site Access Alejandro Cruz, Àngels González-Lafont, José M. Lluch Inflammation is at the base of many different diseases. Leukotrienes (LTs) are pro-inflammatory mediators derived from arachidonic acid (AA), which play significant roles in acute […]
Different Structures—Similar Effect: Do Substituted 5-(4-Methoxyphenyl)-1H-indoles and 5-(4-Methoxyphenyl)-1H-imidazoles Represent a Common Pharmacophore for Substrate Selective Inhibition of Linoleate Oxygenase Activity of ALOX15? Zhuravlev, A.; Cruz, A.; Chen, X.; Aksenov, V.; Golovanov, A.; Lluch J. M.; Kuhn, H.; González-Lafont, À. Ivanov I. Mammalian 15-lipoxygenases (ALOX15) are lipid peroxidizing enzymes that exhibit variable functionality in different cancer […]
Exploring 14S-HpDHA binding modes and its negative allosteric modulation in hALOX12-catalyzed MaR1 biosynthesis Pedro Martínez Zaragoza La resposta inflamatòria està present en un gran nombre de malalties com a defensa del cos contra lesions i infeccions. Generalment, consta de dues fases. En la primera, es produeix la biosíntesi de substàncies com leucotriens i prostaglandines. Seguidament, […]
Functional Characterization of Mouse and Human Arachidonic Acid Lipoxygenase 15B (ALOX15B) Orthologs and of Their Mutants Exhibiting Humanized and Murinized Reaction Specificities Kakularam, K. R.; Canyelles-Niño, M.; Chen, X.; Lluch J. M.; González-Lafont, À. González-Lafont; Kuhn, H. The arachidonic acid lipoxygenase 15B (ALOX15B) orthologs of men and mice form different reaction products when arachidonic acid […]
Hydroperoxidation of Docosahexaenoic Acid by Human ALOX12 and pigALOX15-mini-LOX Canyelles-Niño, M.; González-Lafont, À.; Lluch, J.M. Human lipoxygenase 12 (hALOX12) catalyzes the conversion of docosahexaenoic acid (DHA) into mainly 14S-hydroperoxy-4Z,7Z,10Z,12E,16Z,19Z-docosahexaenoic acid (14S-H(p)DHA). This hydroperoxidation reaction is followed by an epoxidation and hydrolysis process that finally leads to maresin 1 (MaR1), a potent bioactive specialized pro-resolving mediator (SPM) […]
Estudi de la conversió del leucotriè A4 a leucotrieno B4 impulsado por leucotriè A4 hidrolasa Miquel Canyelles Niño LTA4H is a bifunctional zinc metalloenzyme that converts leukotriene A4 (LTA4) into leukotriene B4 (LTB4), one of the most potent chemotactic agents involved in acute and chronic inflammatory diseases. In this reaction, LTA4H acts as an epoxide hydrolase with […]
Understanding how reticulocyte 15-lipoxygenase-1 catalyzes the production of lipoxins in the 5(S),15(S)-DiHpETE biosynthetic pathway Àngels González Lafont La inflamació aguda local dels organismes vius és un mecanisme de defensa en resposta a una lesió tisular o contra una invasió de patògens microbians. Si es descontrola, evoluciona cap a una crònica i pot conduir a una […]
