Description: GGTI-2418 is a highly potent, competitive, and selective geranylgeranyltransferase I (GGTase I) inhibitor. GGTI-2418 inhibits GGTase I and FTase activities with IC50s of 9.5 nM and 53 μM, respectively. GGTI-2418 also increases p27(Kip1) and induces significant regression of breast tumors[1].
In Vivo: GGTI-2418 (100 mg/kg daily or 200 mg/kg every third day; 15 days) significantly inhibits the growth of breast tumor xenografts in nude mice with MDA-MB-231 xenografts[1]. GGTI-2418 (100 mg/kg daily; 5 days) induces regression of ErbB2-driven mammary tumors in ErbB2 transgenic mice[1]. GGTI-2418 inhibits the geranylgeranylation of Rap1 and causes a dramatic decrease in S473 phosphorylation of Akt. GGTI-2418 also upregulates p27 levels in vivo[1]. Animal Model: Nude mice implanted with MDA-MB-231 breast cancer tumors[1] Dosage: 100 mg/kg daily or 200 mg/kg every third day Administration: Injected intraperitoneally; 15 days Result: Inhibited the growth of breast tumor xenografts. Animal Model: ErbB2 transgenic mice[1] Dosage: 100 mg/kg/day Administration: Subcutaneously; 5 days Result: Halted tumor growth and induced massive tumor regression. Tumor decreased by 76% following GGTI-2418 treatment.
In Vitro: GGTI-2418 inhibits GGTase I and FTase activities with IC50s of 9.5±2.0 nM and 53±11 μM, respectively, a 5,600-fold selectivity toward inhibition of GGTase I versus FTase. GGTI-2418 demonstrates competitive inhibition of GGTase I against the H-Ras-CVLL protein with a Ki of 4.4±1.6 nM[1]. GGTi-2418 (10-15 μM; 16 hours) treatment delocalizes FBXL2 and stabilizes IP3R3[2]. Western Blot Analysis[2] Cell Line: HeLa cells Concentration: 10-15 μM Incubation Time: 16 hours Result: Delocalized FBXL2 and stabilized IP3R3.

DC82301 IC-8 IC8 is an ionizable cationic lipid. It has been used in combination with other lipids for the formation of lipid nanoparticles (LNPs). Immunization with severe acute respiratory coronavirus 2 (SARS-CoV-2) spike glycoprotein mRNA in IC8- and manganese-containing LNPs induces IgG responses to SARS-CoV-2 Delta and Omicron variants in mice.1 Administration of mRNA encoding B7-H3 X CD3 bispecific T cell engaging (BiTE) antibodies in IC8-containing LNPs reduces tumor growth in MV4-11 and A375 mouse xenograft models.
DC75721 CL2A-SN38 (Govitecan) CL2A-SN38 is a SN38 derivative with a peptide-linker which can easily react with antibody to form an antibody-drug conjugate (ADC). CL2A-SN-38 is composed of a potent a DNA Topoisomerase I inhibitor SN-38 and a linker CL2A to make antibody drug conjugate (ADC). CL2A-SN-38 provides significant and specific antitumor effects against a range of human solid tumor types. CL2A is a noncleavable complicated PEG8- and triazole-containing PABC-peptide-mc linker. CL2A is cleavable through pH sensitivity, giving rise to bystander effect, and binds the antibody at a cysteine residue via a disulfide bond. .
DC46471 RP101988 RP101988, the major active metabolite of Ozanimod, is a selective, potent S1PR1 (sphingosine-1-phosphate receptor 1) agonist, with EC50s of 0.19 nM and 32.8 nM for S1PR1 and S1PR5, respectivlely.
DC37901 PD-173212 PD-173212 is a small molecule N-type calcium channel blocker.
DC37333 N,N-Diethyl-p-toluamide N,N-Diethyl-p-toluamide is a mosquito repellent.
DC37321 AI3-15902 AI3-15902 is a biochemical.
DC37283 Methyl phenylcarbamate Methyl phenylcarbamate is a biochemical.
DC37252 Ampyrone Ampyrone is a metabolite of AMINOPYRINE with analgesic and anti-inflammatory properties. It is used as a reagent for biochemical reactions producing peroxides or phenols. Ampyrone stimulates LIVER MICROSOMES and is also used to measure extracellular water.
DC37245 Piperonyl butoxide Piperonyl butoxide (PBO) is an organic compound used as a component of pesticide formulations. It is a waxy white solid. It is a synergist. That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone.[1] It is a semisynthetic derivative of safrole.
DC36443 DC-Chol DC-Chol is a cationic cholesterol derivative. DC-Chol, as a component of lipoplexes with DOPE, has been used for transfection of mRNA into A549 cells without affecting cell viability. Incubation of DC-chol/DOPE liposomes or lipoplexes with human whole blood has no effect on neutrophil elastase or β-thromboglobulin levels or the number of platelets and red and white blood cells, indicating hemocompatibility. DC-Chol has also been widely used in the synthesis of liposomes for the delivery of siRNA, DNA, and chemotherapeutic agents into cells and mice.
