Aspergillus fumigatus	0.016 to 16 mg/liter	48 hours	To evaluate the in vitro antifungal activity of Isavuconazole against wild-type and azole-resistant A. fumigatus isolates. Results showed that the MIC of Isavuconazole was 0.5 mg/liter for wild-type and G54W mutant, 4 mg/liter for M220I mutant, and 8 mg/liter for TR34/L98H mutant.	Antimicrob Agents Chemother. 2015 May;59(5):2855-66
HEK293 cells	2.5 µM	15 minutes	To evaluate the inhibitory effect of Isavuconazole on OATP1B1, results showed an IC50 of 2.5 µM, indicating strong inhibition of OATP1B1	Pharmaceutics. 2022 Mar 23;14(4):694
Rhizopus oryzae clinical isolates	0.125 μg/ml		Evaluated in vitro antifungal activity against R. oryzae, showing fungicidal effect	Antimicrob Agents Chemother. 2014;58(4):2450-3
Rhizopus delemar clinical isolates	0.125-1.00 μg/ml		Evaluated in vitro antifungal activity against R. delemar, showing fungicidal effect (MFC equal to MIC)	Antimicrob Agents Chemother. 2014;58(4):2450-3
Cryptococcus neoformans H99	0.03 μg/ml		Evaluate the in vitro activity of Isavuconazole against Cryptococcus neoformans	Antimicrob Agents Chemother. 2016 Aug 22;60(9):5600-3
Candida auris (MRL 35368)	0.25 mg/ml	24 hours	To determine the minimum inhibitory concentration (MIC) of Isavuconazole against Candida auris. Results showed an MIC of 0.25 mg/ml for Isavuconazole.	Antimicrob Agents Chemother. 2021 Aug 17;65(9):e0054921

Mice	Immunocompetent murine model of disseminated aspergillosis	Oral gavage	0.25, 1, 4, 16, 64, 128, 256, and 512 mg/kg/day	Once daily for 14 days	To evaluate the efficacy of Isavuconazole in an immunocompetent murine model of disseminated aspergillosis. Results showed that the efficacy of Isavuconazole depended on both the drug exposure and the MIC of the isolates. The maximum effect (100% survival) was achieved at a prodrug dose of 64 mg/kg for the wild-type isolate, 128 mg/kg for the G54W mutant, and 256 mg/kg twice daily for the M220I mutant. For the TR34/L98H isolate, the highest dose (256 mg/kg twice daily) did not achieve a maximum response.	Antimicrob Agents Chemother. 2015 May;59(5):2855-66
C57BL/6 mice	Exogenous fungal endophthalmitis model	Oral, intravenous, intravitreal	Oral: 122.9 mg/kg; Intravenous: 5 mg/kg; Intravitreal: 10 μg/eye	Oral: once daily for four doses; Intravenous: once daily for four doses; Intravitreal: at 6 h and 24 h postinfection	To evaluate the therapeutic efficacy of isavuconazole via different administration routes in treating A. fumigatus endophthalmitis. Results showed that all routes reduced fungal burden, preserved retinal structure and function, and decreased inflammatory cytokine levels.	Antimicrob Agents Chemother. 2018 Oct 24;62(11):e01537-18
ICR mice	Cryptococcal meningitis model	Oral gavage	120 mg/kg and 240 mg/kg	Twice daily for 10 days	Evaluate the efficacy of Isavuconazole in treating cryptococcal meningitis, showing significant improvement in survival and reduction in brain fungal burden	Antimicrob Agents Chemother. 2016 Aug 22;60(9):5600-3
Mice	Chronic granulomatous disease (CGD) mouse model	Oral	256 mg/kg (equivalent to 122.9 mg/kg of Isavuconazole)	Single dose, observation time points at 1, 3, 6, and 24 hours	To evaluate the distribution and penetration of Isavuconazole in infected tissues. Results showed rapid and efficient distribution of the drug in lung and brain tissues, with transient enrichment in granulomatous lesions. A prominent antifungal effect was observed in infected lung tissue, and the drug efficiently penetrated into the brain.	Antimicrob Agents Chemother. 2019 May 24;63(6):e00524-19
Male ICR mice	Neutropenic mouse model (intratracheal infection with R. delemar)	Oral	215 mg/kg	Three times daily until day 4 postinfection	Compared efficacy of ISA with liposomal amphotericin B (LAmB) in mucormycosis treatment. High-dose ISA (215 mg/kg) significantly improved survival (65% vs 15% placebo) and reduced fungal burden in lungs and brains (~1-log reduction), with efficacy comparable to high-dose LAmB.	Antimicrob Agents Chemother. 2014;58(4):2450-3
BALB/c mice	Immunocompromised murine model of disseminated candidiasis	Oral	20 mg/kg	Twice daily for 28 days	To evaluate the in vivo efficacy of Isavuconazole against Candida auris. Results showed an average survival rate of 50% in the ISA-treated group, with no significant reduction in kidney tissue fungal burden.	Antimicrob Agents Chemother. 2021 Aug 17;65(9):e0054921
ICR/Swiss mice	Neutropenic murine disseminated candidiasis model	Oral-gastric gavage	10, 40, 160, 640 mg/kg	Single dose, 24-hour or 96-hour treatment period	To characterize the pharmacodynamic properties of isavuconazole and determine its PK/PD targets against Candida species. Results showed that the AUC/MIC ratio correlated best with efficacy (R2=0.84), and PD targets for non-albicans Candida species were significantly lower than those for C. albicans.	Antimicrob Agents Chemother. 2013 Nov;57(11):5642-8
