Kobe0065 is a small-molecule inhibitor of the H-Ras–c-Raf-1 interaction, competitively inhibiting the binding of H-Ras·GTP to the c-Raf-1 Ras-binding domain with a Ki value of 46 ± 13 μM. By disrupting the Ras–Raf association, Kobe0065 suppresses downstream RAS/RAF/MEK/ERK signaling pathway activation, leading to inhibition of cancer cell proliferation and induction of apoptosis in Ras-transformed cells.

Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
