L-Thyroxine
(Synonyms: T4, NSC 36397, Levothyroxine) Copy Product Info
L-Thyroxine (NSC 36397) is the major hormone derived from the thyroid gland. L-Thyroxine (NSC 36397) is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. L-Thyroxine (NSC 36397) is released from thyroglobulin by proteolysis and secreted into the blood. L-Thyroxine (NSC 36397) is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.

L-Thyroxine AI Summary
L-Thyroxine exhibits a wide range of biological activities, with notable binding affinity and bioactivity across several assays. It has a relative binding affinity of 100.0 when compared to L-T4 in prealbumin binding assays and demonstrates a moderate to strong binding energy of 10.3 kCal mol-1. The compound shows potential in inhibiting TTR-mediated fibrillogenesis with an IC50 value of 10500 nM and demonstrates high activity in promoting angiogenesis, evident in fertilized chicken egg membranes and Matrigel plug assays. In transporter assays, L-Thyroxine acts as both an inhibitor and substrate, with varying Km values in different cell models, indicating interactions with multiple transporters like OATPs and OCT1. It also affects the uptake of thyroxine and triiodothyronine in Xenopus laevis oocytes. In terms of antiviral activities, it shows some inhibition against SARS-CoV-2 in different cell lines, although the effectiveness varies. Regarding enzymatic activity, L-Thyroxine does not exhibit significant activity towards human UGT enzymes but does show moderate inhibition towards human HDAC6. It also affects specific cell signaling pathways and receptors, including PPARgamma, RXRalpha, THRalpha, and THRbeta, and demonstrates selective inhibition towards certain viral entry mechanisms and enzymes like PDE4D. The compound indicates no observable liver toxicity in specific assays but displays moderate hepatotoxicity in others, suggesting nuanced interactions depending on context and conditions. The bioactivities of L-Thyroxine suggest potential therapeutic applications, but further research is needed to fully understand its mechanisms and effects..
