Ascr#10
Ascr#10 (Asc-C9) is an orally active thermogenesis inducer and insecticide that can be obtained from Monochamus alternatus. Ascr#10 binds to the insect adipokinetic hormone (AKH) receptor (Ka=272 µM) and stimulates mitochondrial biogenesis via the PGC1α-UCP4 axis. Consequently, Ascr#10 induces UCP4-mediated uncoupled respiration, reduces the ATP/ADP ratio and accelerates lipid mobilization, thereby driving the thermogenesis process. Ascr#10 delays pupation and exerts specific chemotaxis toward dispersive fourth-stage pinewood nematode LIV larvae. Ascr#10 promotes cold acclimation of Monochamus alternatus larvae through metabolic inhibition and cryoprotectant accumulation, enhancing their survival rate under cold stress. Ascr#10 also induces browning of white adipose tissue and activates brown adipose tissue in mice, thereby helping the body resist cold and tumor growth. Ascr#10 can be widely applied to research related to pine wilt disease, lung tumors and cold stress.

Biological Activity
Ascr#10 (300 nM) activates AKHR in transfected Drosophila S2 cells, triggering a greater than 60% maximum increase in intracellular Ca2+ fluorescence intensity[2].
Ascr#10 (3 aM-3 µM; 72 h) increases fecundity of native Bursaphelenchus xylophilus isolate US1 at concentrations of 3 aM, 3 fM, and 3 pM after 72 h incubation[4].
Ascr#10 (0.1 nM; 10 days) drives gene expression changes linked to metabolic depression and accumulation of cryoprotectants like glycerol, trehalose, and sorbitol in last-instar larval Monochamus alternatus[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Ascr#10 (10 mg/kg; i.p. injection; every 2 days; 4 weeks) activates BAT and induces subcutaneous WAT browning in mice to enhance thermogenesis and cold tolerance, while also inhibiting lung tumor growth[2].
Ascr#10 (0.1 nM; mixed into artificial diet; continuous feeding; 10 days) enhances cold hardiness in 5th instar Monochamus alternatus larvae, reducing LT50 by 3.2 °C via metabolic depression and upregulation of cryoprotectant synthesis genes[5].

Result:Markedly decreased supercooling points from day 4 of treatment.
Reduced lethal temperature causing 50% mortality (LT50) to -15.4 °C, which was 3.2 °C lower than control.
Identified 1601 differentially expressed transcripts, with 78 of 100 genes in the "metabolic process" GO term downregulated.
Significantly upregulated genes encoding enzymes for cryoprotectant synthesis (trehalose-phosphate phosphatase, glycogen phosphorylase, aldose-1-epimerase, aldo-keto reductase, glucose-6-phosphate isomerase).
Significantly downregulated enolase (a TCA cycle enzyme).
