MedKoo Cat#: 121056 | Name: BSP16

Description:

WARNING: This product is for research use only, not for human or veterinary use.

BSP16, also known as LF250, is a potent, orally available STING agonist. BSP16 strongly activates STING signaling in human and mouse cells and binds STING as a homodimer. In vivo studies revealed that BSP16 is well tolerated, has an excellent pharmacokinetic profile as an oral drug, and induces tumor regression and durable antitumor immunity. The promising bioactivities of BSP16 make it valuable for further development as an antitumor agent.
