The present invention describes compounds that are antifungal agents, useful for the treatment of, for example, fungal infections and related conditions. The present invention further describes a novel chemotype useful for the treatment of fungal infections and other diseases that involve fungal infection.
Fungal infections are a growing problem in numerous medical settings. Modern medical practices including anticancer chemotherapies, immunosuppressive drugs, broad spectrum antibiotics that disrupt the microbiome and indwelling medical devices that disrupt and breach the protective immune system. This creates an opening for infection by opportunistic fungal pathogens. Fungal infections are most common in immunocompromised patients afflicted with HIV or undergoing cancer therapies, hematological stem cell replacement, or organ transplants. Fungal infections can also occur in immunocompetent individuals and the most common cause is from skin and soft tissue wounds resulting from traumatic injury. Significant morbidity is evident with these types of injuries as the local invasive infections often require frequent and extensive surgical debridement in conjunction with systemic antifungal therapy. Nevertheless, amputations are still needed in many of the cases and mortality can be as high as 25%. In both immunosuppressed and immunocompetent patients, the most common fungal pathogens are Candida, Aspergillus, Cryptococcus, Mucorales and Fusarium spp. and infections are associated with a significant incidence of treatment failure and high mortality. Invasive Candidiasis (IC) is the fourth leading healthcare associated bloodstream infection in the US and is associated with a 47% mortality rate. Invasive Aspergillosis (IA) is becoming a dominant invasive fungal disease in hematological oncology, organ transplant and exacerbated chronic obstructive pulmonary disease. The incidence of IA in hematopoietic stem cell transplants has been reported to be as high as 15% with mortality rates ranging from 20% to 50%.

is, for the purposes of the present invention, considered a heteroaryl unit. When a fused ring unit contains heteroatoms in both a saturated and an aryl ring, the aryl ring will predominate and determine the type of category to which the ring is assigned. For example, 1,2,3,4-tetrahydro-[1,8]naphthridine having the formula:
is, for the purposes of the present invention, considered a heteroaryl unit.
Whenever a term or either of their prefix roots appear in a name of a substituent the name is to be interpreted as including those limitations provided herein. For example, whenever the term “alkyl” or “aryl” or either of their prefix roots appear in a name of a substituent (e.g., arylalkyl, alkylamino) the name is to be interpreted as including those limitations given above for “alkyl” and “aryl.”
The term “substituted” is used throughout the specification. The term “substituted” is defined herein as a moiety, whether acyclic or cyclic, which has one or more hydrogen atoms replaced by a substituent or several (e.g., 1 to 10) substituents as defined herein below. The substituents are capable of replacing one or two hydrogen atoms of a single moiety at a time. In addition, these substituents can replace two hydrogen atoms on two adjacent carbons to form said substituent, new moiety or unit. For example, a substituted unit that requires a single hydrogen atom replacement includes halogen, hydroxyl, and the like. A two hydrogen atom replacement includes carbonyl, oximino, and the like. A two hydrogen atom replacement from adjacent carbon atoms includes epoxy, and the like. The term “substituted” is used throughout the present specification to indicate that a moiety can have one or more of the hydrogen atoms replaced by a substituent. When a moiety is described as “substituted” any number of the hydrogen atoms may be replaced. For example, difluoromethyl is a substituted C1 alkyl; trifluoromethyl is a substituted C1 alkyl; 4-hydroxyphenyl is a substituted aromatic ring; (N,N-dimethyl-5-amino)octanyl is a substituted C8 alkyl; 3-guanidinopropyl is a substituted C3 alkyl; and 2-carboxypyridinyl is a substituted heteroaryl.

Fungal MIC Protocol: RPMI/MOPS media (Roswell Park Memorial Institute/3-morpholinopropane-1-sulfonic acid media) is prepared by dissolving 8.4 grams RPMI 0.1640 (Sigma cat #R1383), 34.52 grams MOPS buffer (Sigma cat #M3.183) and 2 grains glucose in 900 mL deionized water. The pH is adjusted to 7.0 with NaOH and filter sterilized. 0.1 mL, of a stock spore suspension (or loop from frozen stock) is inoculated to a 75 mL tissue culture flask (Falcon cat #353136) containing 50 mL of Potato Dextrose Agar (PDA, 24 grams PD broth (Fisher cat #DF 0549179), 20 grams agar (Fisher cat #BP 1423500) per liter water). Aspergillus and Fusarium strains are grown at 35° C. and Mucor strains are grown at room temperature for 3-5 days. Spores are harvested by flooding the flask with 5 mL phosphate buffered saline (PBS) pH 7.4+0.1% Tween-20 and several glass beads (Fisher cat #S800243) are added to aid in agitation. The supernatant is removed and the OD530 of a 1:100 dilution is measured. Spores are diluted in RPMI/MOPS to a final OD530 of 0.002 for Aspergillus and an OD530 of 0.005 for Fusarium and Mucor. The final concentration of spores is approximately 2×104 cfu/mL. Test compound(s) are diluted to 200 ug/mL in RPMI/MOPS (28 ul of 1.0 mg/mL DMSO stock in 1400 ul media). Ten (10) serial dilutions are prepared with RPMI/MOPS in a 96-well round bottom plate (Fisher cat #353136). For Mucor strains a sterile flat-bottom 96-well plate is used. 50 μl of compound dilutions in duplicate are added to a sterile 96-well round bottom plate. 50 ul of diluted spores are added to the compound-containing plates. Control wells include 1) compound but no cells and 2) spores but no compound. Mix the plates gently by hand, place in ziplock bags and
incubate at 35° C. for 48 hours. Score the MIC visually (lowest concentration of compound showing >50% growth inhibition) using an inverted mirror. For Mucorales strains the plates are read at OD530 and the concentration of compound that shows 50% growth inhibition is the MIC-50.
Candida Minimal Inhibitory Concentration (MIC): RPMI/MOPS media is prepared by dissolving 8.4 g RPMI 1640, 34.52 g MOPS buffer and 2 g glucose in 900 mL water. The pH is adjusted to 7.0 with NaOH. The total volume is brought to 1 L and the resulting solution is filter sterilized. The Candida stock is streaked on a Yeast extract Peptone Dextrose (YPD) agar plate and grown at 35° C. for isolation of single colonies. Compounds of the disclosure are diluted to 200 μg/mL in RPMI/MOPS (4.8 ul of 10 mg/mL DMSO stock in 240 ul media). Ten (10) 1:2 serial dilutions are prepared in RPMI/MOPS in a 96-well round bottom plate. Fifty (50) μl of compound dilutions are transferred in duplicate to a sterile tissue culture-treated 96-well flat-bottom, black-sided polypropylene plate. A single colony of Candida from the YPD plate is re-suspended in 5 mL phosphate buffered saline (BS) and optical density (OD) at 600 nm is measured. The suspension is adjusted to OD=1.0 and a 1:1000 dilution is prepared in RPMI/MOPS. Fifty (50) ul aliquots of the diluted yeast are added to the plates containing 50 μL of compound to all wells except 12E-H. Control wells include: 12 A-D cells, no compound and 12 E-H no cells, no compound. The plates are mixed gently by hand and placed in Ziplok bags in a 35° C. incubator. The OD600 is measured at 24 and 48 hours. The lowest concentration of a compound that shows a significant reduction in fungal growth is recorded as the MIC and MIC-50 is the concentration of compound that shows 50% growth inhibition
