Fue dise\u00f1ado y sintetizado en UCLA por el grupo de qu\u00edmica m\u00e9dica de Michael Jung, junto con los laboratorios de Christofk y Lowry, y se describi\u00f3 por primera vez en el <em>Journal of Medicinal Chemistry<\/em> en 2021. Los investigadores suelen buscarlo junto con PP405, el inhibidor t\u00f3pico del MPC que Pelage Pharmaceuticals est\u00e1 llevando a ensayos cl\u00ednicos, porque ambos proceden del mismo programa de investigaci\u00f3n de UCLA.<\/p>\n<h2>De d\u00f3nde viene JXL-069<\/h2>\n<p>El punto de partida fue UK-5099, un inhibidor del MPC conocido desde hace d\u00e9cadas. En un estudio en ratones de 2017, el equipo de UCLA demostr\u00f3 que bloquear el MPC en las c\u00e9lulas madre del fol\u00edculo piloso hac\u00eda que esas c\u00e9lulas produjeran m\u00e1s lactato y aceleraba el paso de la fase de reposo (tel\u00f3geno) a la fase de crecimiento (an\u00e1geno) del ciclo del pelo (Flores et al., 2017).<\/p>\n<p>Para encontrar mejores inhibidores, los qu\u00edmicos prepararon una amplia serie de an\u00e1logos de UK-5099 y los numeraron de JXL001 a JXL088. JXL001 es el propio UK-5099. JXL069 es el an\u00e1logo con un n\u00facleo de 7-azaindol y un grupo 3,5-bis(trifluorometil)bencilo (Liu et al., 2021).<\/p>\n<h2>Qu\u00e9 muestra la investigaci\u00f3n publicada<\/h2>\n<ul>\n<li>En ensayos celulares, JXL069 aument\u00f3 la producci\u00f3n de lactato, un indicador de inhibici\u00f3n del MPC.<\/li>\n<li>En c\u00e9lulas permeabilizadas, JXL069 bloque\u00f3 la respiraci\u00f3n alimentada por piruvato con una IC50 de unos 42,8 nM, frente a unos 140 nM de UK-5099. Esto lo hace aproximadamente tres veces m\u00e1s potente en este ensayo.<\/li>\n<li>El an\u00e1logo de 7-azaindol fue mucho m\u00e1s potente que las versiones muy similares de 4-azaindol y 6-azaindol.<\/li>\n<li>El mismo art\u00edculo prob\u00f3 por v\u00eda t\u00f3pica m\u00e1s de diez an\u00e1logos en ratones rasurados y describi\u00f3 una entrada m\u00e1s r\u00e1pida en el ciclo del pelo con varios de ellos. El texto no destaca a JXL069 entre los compuestos probados en ratones.<\/li>\n<\/ul>\n<p>Todo esto es investigaci\u00f3n en c\u00e9lulas y en ratones. No hay estudios publicados de JXL-069 en humanos.<\/p>\n<h2>C\u00f3mo act\u00faa JXL-069: el mecanismo del MPC<\/h2>\n<p class=\"translation-block\">El MPC es un complejo proteico de la membrana mitocondrial interna que transporta el piruvato al interior de las mitocondrias. Lo identificaron en 2012 dos grupos independientes (Bricker et al., 2012; Herzig et al., 2012). Cuando se bloquea el MPC, una mayor parte del piruvato se convierte en lactato en el citoplasma. El trabajo de UCLA sugiere que este desplazamiento hacia la producci\u00f3n de lactato es una de las se\u00f1ales que activa las c\u00e9lulas madre del fol\u00edculo en reposo en ratones.
