The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

C75 trans (trans-C75, (±)-C75) is a novel, potent synthetic inhibitor of fatty acid synthase (FAS/FASN) with IC50 of 35 μM and 50 μM in clonogenic assays and spheroid growth assay, respectively. C75 is used as a tool for studying fatty acid synthesis in metabolic disorders and cancer.

Targets

FASN ^[1] (clonogenic assay)	FASN ^[1] (spheroid growth assay)
35 μM	50 μM

In vitro

C75 is toxic to prostate cancer cells. C75 reduces cell migration, while enhances radiation-induced clonogenic kill and enhances the spheroid growth delay induced by radiation exposure. Apoptosis induction by radiation exposure is enhanced by C75 treatment.^[1] C75 inhibits fatty acid synthesis and growth of established cancer cell lines from neu-N transgenic mice. C75 reduces the proliferation and expression of FAS, neu, and related genes in mammary epithelium.^[2]

In vivo

C75 inhibits fatty acid synthesis and in vivo mammary cancer development. C75 treatment prevents mammary cancer development and retards mammary development in neu-N transgenic mice.^[2]

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines PC3 cells, LNCaP cells Concentrations 5 μM, 25 μM, 35 μM, 50 μM Incubation Time 3 h, 6 h, 24 h Method PC3 cells are seeded in 25 cm² flasks at 10⁵ cells/flask. When cultures are in exponential growth phase, media is removed and replaced with fresh drug-containing media. Cells are then incubated for 24 h at 37℃ in 5% CO₂. To determine optimal sequencing of therapeutic agents, three different combination treatment schedules are assessed: 1. radiation and C75 administered simultaneously; 2. radiation administered 24 h before C75; and 3. radiation administered 24 h after C75. After treatment, cells are seeded for clonogenic survival assay.
