Batimastat sodium salt

Animal Administration [5][6]
Mice[5] Six-weeks-old female BALB/c mice are used. Mice are treated i.p. with Batimastat (BB-94, 50 mg/kg) 1 h before and 24 h post-infection. Batimastat is suspended at 50 mg/mL in DMSO and stored frozen at -20°C. Prior to use, it is diluted 20-fold in phosphate buffered saline (PBS), and 500 μL are injected into animals. Control mice are injected with 500 μL of 5% DMSO in PBS. Animals are sacrificed 48 h after i.c. challenge. Rats[6] Female Sprague-Dawley rats are administered a single physiological dose of E2 (40 μg/kg in a 0.9% NaCl, 0.4% EtOH vehicle) by intraperitoneal (i.p.) injection at the indicated time intervals prior to tissue collection at necropsy. This in vivo dose level of E2 has been shown to induce changes in uterine wet weight, tissue architecture, and gene expression characteristic of estrogen receptor activation. For all other experiments, animals are i.p. administered a single 40 μg/kg bolus of E2 4 h prior to tissue harvest, while control animals receive vehicle only in all studies. Batimastat is administered i.p. at a dose level (40 mg/kg in a 1× PBS, 0.1% Tween-20 vehicle) shown to be effective at inhibiting MMPs in vivo 4 h prior to E2 or saline control.
