In each experiment, 16 aliquots of 15 μL of Geldanamycin (300 μM in 1% DMSO) were injected into 1.3 mL of protein (31 μM in 20 mM Tris-HCl, pH 7.5, 1 mM EDTA) at 25°C, and the resulting data were fit after subtracting the heats of dilution. Heats of dilution were determined in separate experiments from addition of Geldanamycin into buffer and buffer into protein. No evidence for binding of DMSO in the nucleotide binding site was observed. Titration data were fit using a nonlinear least-squares curve-fitting algorithm with three floating variables: stoichiometry, binding constant (Kb = 1/Kd), and change of enthalpy of interaction (ΔH°). The dissociation constant estimated for Geldanamycin binding to intact yeast Hsp90 was 1.22 μM, and for binding to Hsp90 N-terminal domain was 0.78 μM. No meaningful heat was observed with binding to the C-terminal fragment.Cell experiment [2]:Cell linesA2780 cellsPreparation methodThe solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.Reaction Conditions0.001 ~ 10 μM; 3 hrsApplicationsIn human ovarian cell line A2780, Geldanamycin caused a dose-dependent G2 arrest and reversible inhibiton of entry into the S phase.Animal experiment [3]:Animal modelsMice bearing FRE/erbB-2 tumorsDosage form50, 100, 200 and 400 mg/kg; i.p.; b.i.d., for 5 daysApplicationsIn mice bearing FRE/erbB-2 tumors, Geldanamycin (50 mg/kg) shows 30% inhibition on p185-associated phosphotyrosine levels.Other notesPlease test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.References:[1]. Roe SM, Prodromou C, O"Brien R, Ladbury JE, Piper PW, Pearl LH.

BackgroundGeldanamycin, a crystalline antimicrobial compound derived from the culture filtrates of Streptomyces hygroscopicus var. geldanus var. nova., is a potent and specific inhibitor of heat shock protein 90 (Hsp90) that specifically binds to the unique ATP binding pocket of Hsp90 in a stable and pharmacologically specific manner. As an antimicrobial agent, geldanamycin exhibits moderate activity against protozoa, bacteria and fungi as well as parasite Syphacia oblevata and cell cultures of L-1210 and KB. Recent studies have shown that geldanamycin also inhibits the function of glucocorticoid receptor and endothelium-dependent relaxation of the rat aorta, mesentery and middle artery.ReferenceBucci M, Roviezzo F, Cicala C, Sessa WC, Cirino G.
