( )-biocytin

Biocytin is a classical neuroanatomical tracer commonly used to map brain connectivity. Biocytin is a conjugate of D-biotin and L-lysine, where the carboxylate of D-biotin is coupled with the ϵ-amine of L-lysine via a secondary amide bond.

N-(Propargyl-PEG4)-biocytin is a polyethylene glycol (PEG)-based linker designed for constructing proteolysis targeting chimeras (PROTACs) [1].

N-(Azido-PEG4)-biocytin serves as a PEG-based PROTAC linker for PROTAC synthesis[1].

Selective TRPC5 activator (EC50 = 1.4 μM in a calcium influx assay, 1.3 μM in whole cell patch clamp assay). Displays >14.5-fold selectivity for TRPC5 over other TRP channels (EC50 = 20.6 μM for TRPM8). Also activates TRPC1:5 and TRPC4:5 heteromers.
