TAU-PROTEIN TARGETING COMPOUNDS AND ASSOCIATED METHODS OF USE
-
Paragraph 1156; 1157, (2021/02/12)
The present disclosure relates to bifunctional compounds, which find utility as modulators of tan protein. In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a VHL or cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds tan protein, such that tan protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of tan. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of tan protein. Diseases or disorders that result from aggregation or accumulation of tan protein are treated or prevented with compounds and compositions of the present disclosure.

An efficient conversion of biorenewable ferulic acid into bio-catechol has been developed. The transformation comprises two consecutive defunctionalizations of the substrate, that is, C?O (demethylation) and C?C (de-2-carboxyvinylation) bond cleavage, occurring in one step. The process only requires heating of ferulic acid with HCl (or H2SO4) as catalyst in pressurized hot water (250 °C, 50 bar N2). The versatility is shown on a variety of other (biorenewable) substrates yielding up to 84 % di- (catechol, resorcinol, hydroquinone) and trihydroxybenzenes (pyrogallol, hydroxyquinol), in most cases just requiring simple extraction as work-up.

Eleven new 3 ′,4 ′- seco acyclic nucleosides (4-14) were prepared by nucleophilic substitution of protected pyrimidine bases on ethyl 3,3-diethoxypropanoate (3). Structures were characterized spectroscopically and a brief analysis of their conformation in solution was performed by the vicinal coupling constants 3 J H 2′ aH 3′ and 3 J H 2′ bH 3′. In solid state, compound 6 forms a homodimer linked by hydrogen bonding. In preliminary tests all compounds show low toxicity and gentle activity against HIV-1 RT in vitro.
