Hodgkinsine is a pyrrolidinoindoline alkaloid that has been found inP. colorataand has analgesic activity.1It increases latency to paw licking in the hot plate test and latency to tail withdrawal in the tail-flick test in mice when administered at a dose of 5 mg/kg.

Hodgkinsine B is an alkaloid and isomer of hodgkinsine that has analgesic activity.1It increases the latency to tail withdrawal in the tail-flick test in mice when administered at a dose of 10 mg/kg.

Mitoguazone (Methyl-GAG) 是一种可透过血脑屏障的选择性的 S-腺苷-蛋氨酸脱羧酶 (S-adenosyl-methionine decarboxylase) 抑制剂,可破坏多胺的生物合成。Mitoguazone 是一种具有抗肿瘤活性的合成多羰基衍生物,可抑制 HIV DNA 整合到单核细胞和巨噬细胞中的细胞 DNA 中,诱导细胞凋亡 (apoptosis)。Mitoguazone 具可用于预防急性白血病,霍奇金淋巴瘤和非霍奇金淋巴瘤。
Darinaparsin is a dimethylated arsenic linked to glutathione. It is cytotoxic to DU145, LNCaP, and PC3 prostate cancer cells (IC50s = 5-10 µM) and patient-derived primary prostate cancer cells (IC50s = 2.5-20 µM), as well as Jurkat T cell lymphoma and L540 Hodgkin lymphoma cells (IC50s = 2.7 and 1.3 µM, respectively). [1][2] It decreases the tumor-initiating subpopulation in DU145 and PC3 cells and halts the cell cycle in the G2/M phase. Darinaparsin decreases transcription of Gli-2, a transcription factor that mediates Sonic hedgehog signaling, when used at a concentration of 1.5 but not 3 µM. It decreases SHP1 phosphatase activity and increases ERK phosphorylation. [2] Darinaparsin reduces tumor growth in DU145 and PC3 prostate cancer mouse xenograft models when administered at a dose of 100 mg/kg every other day.[1]
