Gedunin is novel and highly potent Hsp90 inhibitor that exhibits anticancer and antimalarial activity. It induces Hsp90-dependent client protein degradation and displays antiproliferative activity in vitro (IC50 values are 3.22, 8.84 and 16.8 μM in SKBr3, MCF-7 and CaCo-2 cancer cell lines respectively). Decreases ovarian cancer cell proliferation in vitro and may enhance cisplatin-induced reduction in proliferation (CAT.No 3387). Also exhibits antimalarial activity against P. falciparum (IC50 values are 0.14 and 3.1 μM in parasite development and [3H]-hypoxanthine uptake assays respectively).

| Additional Infomation |
Gedunin is a pentacyclic triterpenoid natural product found particularly in Azadirachta indica and Cedrela odorata. It has a role as an antimalarial, an antineoplastic agent, a Hsp90 inhibitor and a plant metabolite. It is a limonoid, an acetate ester, an epoxide, an enone, a member of furans, a pentacyclic triterpenoid, an organic heteropentacyclic compound and a lactone. Gedunin has been reported in Cedrela salvadorensis, Melia azedarach, and other organisms with data available. |
Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.

InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently. (Please use freshly prepared in vivo formulations for optimal results.) |
