Ajoene is a disulfide that has been found inA. sativumand has diverse biological activities, including antibacterial, anticancer, antiplatelet, and antioxidant properties.1,2,3,4It is active against Gram-positive (MICs = 5-160 µg/ml) and Gram-negative bacteria (MICs = 136-200 µg/ml), as well as yeasts (MICs = 10-20 µg/ml).1Ajoene is cytotoxic to mouse melanoma cells (IC50= 18 µM), as well as human colon, lung, mammary, and pancreatic cancer cells (IC50s = 7-41 µM).2It reduces tumor growth in a B16/BL6 mouse model of melanoma when administered at a dose of 25 mg/kg every other day and decreases the number of lung metastases when administered prior to tumor cell inoculation at doses ranging from 1-25 mg/kg. It inhibits ADP- or collagen-induced platelet aggregation in isolated baboon platelets when used at concentrations ranging from 75 to 150 µg/ml and in platelet-rich plasma isolated from baboons when administered at a dose of 25 mg/kg.3Ajoene (25 mg/kg) prevents thrombus formation on damaged arterial walls in heparinized pigs in anin situmodel of thrombogenesis.5It also reduces high-fat diet-induced hepatic steatosis, histopathological markers of liver damage, thiobarbituric acid reactive substances (TBARS) formation, and protein oxidation in a mouse model of non-alcoholic fatty liver disease (NAFLD).4 1.Naganawa, R., Iwata, N., Ishikawa, K., et al.Inhibition of microbial growth by ajoene, a sulfur-containing compound derived from garlicAppl.

3-beta-O-(trans-p-Coumaroyl)maslinic acid is a DNA polymerase B inhibitor. It shows antimicrobial activity on Gram-positive bacteria and yeasts.

Quinolactactin A is a quinolone fungal metabolite originally isolated from Penicillium. It inhibits TNF production induced by LPS in murine peritoneal macrophages (IC50 = 12.2 μg/ml). It is not active against a variety of bacteria, fungi, and yeasts. Quinolactacin A is a mixture of quinolactacin A1 and A2.

Isodictamnine is phototoxic to certain bacteria and yeasts in long wave UV light.

3-beta-O-(trans-p-Coumaroyl)maslinic acid shows antimicrobial activity on Gram-positive bacteria and yeasts.

Naftifine Hydrochloride is the hydrochloride salt form of naftifine, an allylamine derivate with synthetic broad-spectrum antifungal activity. Although the exact mechanism through which naftifine hydrochloride exerts its effect is unknown, it appears to selectively inhibit the enzyme squalene 2, 3-epoxidase, thereby inhibiting the biosynthesis of sterol. This results in a decreased amount of sterols, especially ergosterol which is the primary fungal membrane sterol, and a corresponding accumulation of squalene in fungal cells. Naftifine hydrochloride (Naftifine HCl) can be fungicidal as well as fungistatic to yeasts depending on the concentration and the organisms involved.

Butoconazole Nitrate is the nitrate salt form of butoconazole, a synthetic imidazole derivative with fungistatic properties. Butoconazole nitrate (RS 35887) interferes with steroid biosynthesis by inhibiting the conversion of lanosterol to ergosterol, thereby changing the fungal cell membrane lipid composition. This alters cell permeability and leads to growth inhibition. Butoconazole nitrate is active against many dermatophytes and yeasts. It also contains antibacterial effects against some gram-positive organisms.

Isavuconazole D4 is a deuterium labeled Isavuconazole. Isavuconazole is a triazole prodrug with antifungal activity against yeasts, molds, and dimorphic fungi.

Kalafungin antimicrobial agent that is inhibitory in vitro against a variety of pathogenic fungi, yeasts, protozoa, gram-positive bacteria, and, to a lesser extent, gram-negative bacteria.

Idarubicin, a potent anthracycline antileukemic agent, is orally active in its application. It functions by inhibiting topoisomerase II, thus interfering with DNA replication and RNA transcription. Furthermore, Idarubicin induces DNA damage, inhibits DNA synthesis, and suppresses c-myc expression. It also demonstrates inhibitory effects on the growth of bacteria and yeasts [1] [2] [3] [4] [5].

Parconazole Free Base is used in veterinary as an oral fungicide with a broad-spectrum activity against dermatophytes, yeasts, and others fungi. This compound does not have any antibacterial effect. The mechanism of action involves inhibition of the fungal cytochrome P450 dependent 14alpha-dimethylation of lanosterol to ergosterol.

Naftoxate is an antimicotic. It is effective against both gram-positive and gram-negative bacteria as well as yeasts and other fungi in plant cell culture.

Enfumafungin, a triterpene glycoside extracted from Hormonema carpetanum fungus, acts as an antifungal by inhibiting (1,3)-beta-D-glucan synthase, crucial for fungal cell wall synthesis. It selectively targets yeasts and fungi, excluding Cryptococcus, without affecting Bacillus subtilis growth [1] [2].

Aculeacin A is used to study mutations that lead to antibiotic resistance in Saccharomyces cerevisiae, the inhibition of Candida albicans and the morphogenetic transformation of Candida albicans when treated. Aculeacin A is a lipopeptide that inhibits β-glucan synthesis in yeasts. The inhibition is due to the selective blockage of glucan synthase. Aculeacin A, an amphophilic antibiotic, inhibits the biosynthesis of β−glucan by selective blockage of β(1→3) glucan synthase.

Concanamycin C, a natural macrolide antibiotic, was initially isolated from Streptomyces and identified as an inhibitor of T-cell proliferation in response to concanavalin A (1,2). It exhibits cytotoxicity to fungi, including yeasts, by inhibiting vacuolar-type ATPases (3,4).

Sorbic acid is a natural product that inhibits various bacteria, including sporeformers,
