SW209049 is a stearoyl-CoA 9-desaturase inhibitor. SW209049 exhivits potent activity against H2122 cell with IC50 of 0.13uM.

RBC8 is a specific GTPases RalA/RalB inhibitor by inhibiting the binding of Ral to its effector RALBP1, no inhibition on the GTPases RhoA and Ras.

KRAS inhibitor-9 (DUN09716) is a potent KRAS inhibitor with Kd of 92 μM that blocks the formation of GTP-KRAS and downstream activation of KRAS. KRAS inhibitor-9 causes G2/M cell cycle arrest and induces apoptosis. KRAS inhibitor-9 selectively inhibits the proliferation of NSC-LC cells with KRAS mutation but not normal lung cells

BQU57 selectively inhibits Ral over Ras or Rho and suppresses xenograft tumor growth.

G-573 is an allosteric inhibitor of MEK that is both potent and selective. The IC(50) value for pERK inhibition in HCT116 tumours by G-573 was estimated to be 0.406  µM. The IC(50) values for tumour growth inhibition in HCT116 and H2122 were estimated to be 3.43 and 2.56 µM, respectively. ED(50) estimates in HCT116 and H2122 mouse xenograft models were estimated to be ~4.6 and 1.9 mg/kg/day, respectively.

SW203668 is an irreversible inhibitor of stearoyl-CoA desaturase (IC50 = 54 nM). It is selectively cytotoxic to H2122, H460, HCC44, and HCC95 cell lines that express cytochrome P450 (CYP) isoform CYP4F11 over eight other cancer cell lines that lack CYP4F11 in vitro (IC50s = 22-116 and >10,000 nM, respectively) and ectopic expression of CYP4F11 in SW203668-insensitive H1155 cells results in sensitization to SW203668. In vivo, SW203668 reduces tumor growth rate without reducing sebocyte production in the H2122 wild-type and nonobese diabetic severe combined immunodeficiency (NOD-SCID) mouse xenograft models when administered at doses of 20 and 6 mg/kg, respectively.
