Since misfolding and amyloid aggregation of \u03b1Syn is thought to play a critical role in PD, the aggregation pathway of the protein represents then an obvious target for therapeutic intervention in this disorder. Therefore, understanding the molecular events behind \u03b1Syn amyloid assembly and its inhibition is of high clinical importance. In this context, the discovery of small molecules targeting disease-associated protein aggregation is considered one of the most active therapeutic approaches. From the screening of large libraries of small molecules, potential candidates with different chemical structures were found to modulate the aggregation of distinct amyloid proteins. Notably, poly-aromatic scaffolds belonging to polyphenols and porphyrinoids were predominantly identified by these screenings. Particularly, phthalocyanines were shown to exhibit anti-scrapie activity and inhibition of \u03b1S, tau, and A\u03b2 amyloid assembly. In this work, we report at a residue specific level of resolution the structural and molecular basis for the inhibitory mechanism of a phthalocyanine molecule on ?s fibril amyloid assembly.<\/p>\n","protected":false},"excerpt":{"rendered":" Author: GARRO Hugo Alejandro | email: hgarro@unsl.edu.ar | Neurochemistry and Neuropharmacology<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[17],"tags":[25],"class_list":["post-1344","post","type-post","status-publish","format-standard","hentry","category-session-1","tag-neurochemistry-and-neuropharmacology"],"_links":{"self":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts\/1344","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/comments?post=1344"}],"version-history":[{"count":5,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts\/1344\/revisions"}],"predecessor-version":[{"id":2237,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/posts\/1344\/revisions\/2237"}],"wp:attachment":[{"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/media?parent=1344"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/categories?post=1344"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/csan2023.saneurociencias.org.ar\/index.php\/wp-json\/wp\/v2\/tags?post=1344"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
