“The efficacy of allicin compared with fluconazole in alleviating systemic Candida albicans infections was evaluated both in vitro and in vivo through a systemic candidiasis mouse model. Determination of in vitro minimum inhibitory concentrations (MICs) for different C. albicans isolates revealed that both allicin and fluconazole showed different MICs that ranged from 0.05 to 12.5 μg mL−1 and 0.25 to 16 μg mL−1, respectively. A time–kill study showed a significant effect of allicin (P<0.01) against C. albicans, comparable to that of fluconazole. Scanning electron microscopy observation revealed that, similar to fluconazole, allicin produced structural destruction of C. albicans cell surface at low MIC and lysis or puncture at high MIC concentrations. Treatment of BALB/c mice systemically infected with C. albicans showed that although the allicin treatment (at 5 mg kg−1 day−1) was slightly less efficacious than fluconazole treatment in terms of the fungal load reduction and host survival time, it was still effective

selleck compound library against C. albicans in terms of mean survival time, which increased from 8.4 to 15.8 days. These results demonstrate the efficacy of anticandidal effects of allicin both in vitro and in an animal model of candidiasis and affirm the potential of allicin as an adjuvant therapy to fluconazole. Recently, the Sulfite dehydrogenase incidence of systemic candidiasis, which is caused by Candida spp., predominantly Candida albicans, has increased (Chowta et al., 2007). This increase over the last two decades has caused a rise in the use of antifungal drugs (Pereira-Cenci et al., 2008). Azoles such as fluconazole or ketoconazole are usually used for treatment of systemic fungal infections. However, one of the biggest problems faced in clinical practice is

the emergence of resistance to most of these azole drugs due to mutation (Odds et al., 2003; Looi et al., 2005). Clinically adverse effects are also seen with the use of azoles (Al-Mohsen & Hughes, 1998). Therefore the most urgent challenge in pharmaceutical research is the discovery and development of new antifungals from plant and microbial sources. Allicin (diallyl thiosulfinate), one of the sulfur compounds from garlic, has been shown to possess antifungal activity (Yamada & Azuma, 1977). It has been shown that after crushing fresh garlic cloves, allinase rapidly converts the released allin (precursor of allicin) into allicin (Ankri & Mirelman, 1999). Allitridium (diallyl trisulfide), one of the breakdown products from allicin, has also been found to show antifungal activity in vitro (Davis et al., 2003) and in vivo (Davis et al., 1990).
