Sudachitin
Sudachitin is an orally active compound that potently inhibits mouse PDE1C and human PDE4B, with IC50 values of 5.0 μM and 15.0 μM, respectively. Sudachitin upregulates Sirt1 and PGC‑1α expression in skeletal muscle to regulate energy metabolism and promote mitochondrial biogenesis. Sudachitin improves lipid metabolism, glucose tolerance, insulin sensitivity, energy expenditure, and fatty acid β‑oxidation. Sudachitin activates p38MAPK signaling, induces HSP27 phosphorylation and caspase‑dependent apoptosis, and blocks EGF‑driven keratinocyte migration and proliferation. Sudachitin suppresses LPS‑induced TNF‑α, NO, and iNOS expression in macrophages and shows potent anti‑inflammatory activity. Sudachitin can be used for the research of metabolic syndrome, type 2 diabetes, and psoriasis..

Sudachitin (30 μmol/L; 48 h) significantly upregulates genes involved in mitochondrial biogenesis and glucose transport, and increases mitochondrial density by 2.5-fold in primary mouse skeletal muscle myocytes[1].
Sudachitin (30-100 μM; 24 h) induces caspase-dependent apoptosis in human keratinocyte HaCaT cells, as evidenced by cleaved Bid, caspase-3, and PARP[2].
Sudachitin (30-100 μM; 2-24 h) induces apoptosis in human keratinocyte HaCaT cells via activation of the MKK3/6-p38MAPK pathway, with sustained p38MAPK phosphorylation up to 24 h at 100 μM[2].
Sudachitin (30 μM; 1 h pretreatment followed by EGF stimulation) suppresses EGF-induced ERK1/2 activation in human keratinocyte HaCaT cells, including inhibiting Raf-1 phosphorylation and Elk-1 transcriptional activity[2].
Sudachitin (30 μM; 1 h pretreatment followed by 24 h EGF exposure) inhibits EGF-induced migration and proliferation of human keratinocyte HaCaT cells[2].
Sudachitin (up to 30 μM; 24 h) does not reduce the viability of mouse macrophage-like RAW264 cells[3].
Sudachitin (10-30 μM; 12 h LPS stimulation) significantly suppresses LPS-induced TNF-α production in mouse macrophage-like RAW264 cells when pretreated before LPS stimulation[3].
Sudachitin (3-30 μM; 12 h LPS incubation) dose-dependently inhibits LPS-induced NO production in mouse macrophage-like RAW264 cells, with 30 μM reducing nitrate levels to near-basal levels[3].
Sudachitin (30 μM; 6 h LPS stimulation) pretreatment markedly inhibits LPS-induced TNF-α and iNOS mRNA expression in mouse macrophage-like RAW264 cells[3].
Sudachitin (0.1-100 μM) inhibits recombinant mouse PDE1C activity with an IC₅₀ of 5.0 μM (1 μM cGMP as substrate) and recombinant human PDE4B activity with an IC₅₀ of 15 μM (1 μM cAMP as substrate)e[3].
