The present disclosure relates to bifunctional compounds, which find utility as modulators of tau 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 tau protein, such that tau protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of tau. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of tau protein. Diseases or disorders that result from aggregation or accumulation of tau protein are treated or prevented with compounds and compositions of the present disclosure.

The present invention relates to 14- or 15-membered macrolides substituted at the 4' position of formula (I) and pharmaceutically acceptable derivatives thereof, to processes for their preparation and their use in therapy or prophylaxis of systemic or topical microbial infections in a human or animal body.
large spectrum of applications, poly-functionalized pyridines remain an attractive challenge in modern organic chemistry. We describe the poly-functionalization of halopyridines through a series of sequential and regioselective palladium-catalyzed cross-coupling reactions (Suzuki–Miyaura, Sonogashira and Buchwald–Hartwig reactions). This strategy was applied to the synthesis of several analogs of single

The present disclosure relates to bifunctional compounds, which find utility to degrade and (inhibit) Androgen Receptor. In particular, the present disclosure is directed to compounds, which contain on one end a cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds Androgen Receptor, such that Androgen Receptor is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of Androgen Receptor. The present disclosure exhibits a broad range of pharmacological activities associated with compounds according to the present disclosure, consistent with the degradation/inhibition of Androgen Receptor.

A flow‐based synthesis of diversely functionalized indolizines and their aza‐analogues is described. These drug‐like heterocycles were generated via a tandem Sonogashira/cycloisomerization sequence, starting from widely available 2‐bromopyridines and alkynes, employing a simple catalyst system together with 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) as base. The use of flow technology allows a straightforward
