KARI 201
KARI 201 is an orally active, blood-brain barrier-penetrant bifunctional small molecule. KARI 201 is a selective inhibitor of ASM and an agonist of GHSR-1a. KARI 201 competitively binds ASM, inhibits ASM activity to reduce intracellular ceramide levels, restores lysosomal biogenesis, and repairs impaired autophagic flux in neurons. KARI 201 activates GHSR-1a and induces calcium influx. KARI 201 ameliorates Alzheimer's disease-related pathology, age-related sarcopenia phenotypes, and postoperative ileus-related symptoms. KARI 201 can be used in Alzheimer's disease-related research.

Parmacokinetics
In Vivo
KARI 201 (10 mg/kg; p.o.; daily; 14 days) activates hypothalamic ARC neurons and increases food intake in C57BL/6 mice[2].
KARI 201 (10-30 mg/kg; p.o.; single administration) improves gastrointestinal transit and food intake in postoperative ileus C57BL/6 mice[2].

Animal Model:APP/PS1 (transgenic AD model; 7.5-month-old at start, 9-month-old at analysis)[1]
-
Dosage:1 mg/kg; 5 mg/kg; 10 mg/kg
-
Administration:p.o.; daily; from 7.5 to 9 months of age
-
Result:Suppressed ASM activity dose‑dependently and normalized ASM function at 10 mg/kg independent of Smpd1/ASM expression.
Mitigated Aβ‑tau pathologies, cognitive‑behavioral impairments and neuroinflammation without perturbing APP‑Bace‑1 signaling.
Lowered neuronal ASM‑ceramide while maintaining microglial sphingolipid homeostasis.
Restored autophagic‑lysosomal function and microglial Aβ phagocytosis.
Promoted hippocampal neurogenesis, CA1‑LTP and cerebral BDNF with no toxicity to survival and body weight.
Reversed disease‑relevant transcriptomic disturbances across ribosomal, G‑protein‑signaling and cognition‑associated gene modules.
-
