Description: MAC-545496 is a nanomolar inhibitor of glycopeptide-resistance-associated protein R (GraR). MAC-545496 displays strong binding affinity to the full-length GraR protein (Kd ≤ 0.1 nM). MAC-545496 is an antivirulence agent that reverses β-lactam resistance in Methicillin-resistant strains (MRSA)[1].
Target: Glycopeptide-resistance-associated protein R (GraR)[1]
In Vivo: In vivo, MAC-545496 is effective as a monotherapy for MRSA infected Galleria mellonella larvae. MAC-545496 activity is evidenced by increased survival of the drug-treated larvae as compared to infected untreated ones. This corresponded to concentration-dependent killing of S. aureus in the hemolymph of the larvae observed from the CFUs recovered from the hemolymph 200 min after infection. Treatment of S. aureus-infected larvae with MAC-545496 occurred 30min after infection that mimics acquiring bacterial infection before initiating antimicrobial therapy [1].
In Vitro: MAC-545496 potently synergizes with Cefuroxime; concentrations as low as 0.03 µg/mL (~75 nM) lowers the β-lactam MIC from 512 to 8 µg/mL against S. aureus USA300. MAC545496 also synergizes with Cefuroxime and Oxacillin against a collection of ten S. aureus clinical isolates. In addition, MAC-545496 potentiates the effect of Cefuroxime against representatives of other circulating MRSA strains such as USA100, USA400 and USA500 to different extents, with the exception of CMRSA4, a USA200/EMRSA16 isolate. MAC-545496 also synergizes with the antimicrobial peptides colistin and polymyxin B[1]. MAC-545496 shows inhibition of mprF expression in a concentration-dependent manner; the IC50 value is 0.0376 µg/mL[1]. MAC-545496 also inhibits the citrateinduced biofilm formation in the wild type in a concentration dependent manner[1].

DC72935 JSF-2414 JSF-2414 (JSF2414) is a potent, small molecule GyrB/ParE dual binding inhibitor, simultaneously binds to ATP binding regions of DNA gyrase (GyrB) and topoisomerase (ParE) and displays potent in vitro activity against strains of MRSA, VRSA and VISA.
DC72144 TH-Z145 TH-Z145, a lipophilic bisphosphonate, is a FPPS inhibitor (IC50: 210 nM).
DC71474 VP-4604 VP-4604 is a potent anti-methicillin-resistant Staphylococcus aureus (MRSA) agent. VP-4604 exhibits significant microbial growth inhibition toward Staphylococcus aureus (ATCC 43300) with MIC of 4-8 µg/mL. VP-4604 inhibits the growth of methicillin‐resistant Staphylococcus aureus with growth inhibition >95%.
DC71466 EDA-DA EDA-DA is an unnatural dipeptide building block (an ethynyl-D-alanine and a D-alanine). It incorporates a biorthogonal alkyne group into peptidoglycan (PG) through MurF in the cytoplasmic pathway, which enables selective labeling via a click-chemistry reaction. EDA-DA allows labeling of PG in Gram-positive (B. subtilis), Gram-negative (E. coli and C. trachomatis), Mycobacterium (M. smegmatis) and moss plastids (P. patens) with azide modified fluorescent dyes such as Alexa Fluor 488.
DC70750 Rv1625c agonist V-59 Rv1625c agonist V-59 (V-59) is a specific small molecule agonist of the Mtb adenylyl cyclase Rv1625c, inhibits Mtb growth in macrophages (EC50=0.3 uM) in an Rv1625c-dependent mechanism.V-59 inhibits Mtb growth in cholesterol media (EC50 0.70 uM), but not in media containing the two-carbon fatty acid acetate, or in standard rich growth media.V-59 stimulates Rv1625c to produce cAMP, which is necessary for V-59 to inhibit Mtb growth.Chemically activating Rv1625c via V-59 preferentially inhibits cholesterol utilization in WT Mtb, rather than equally inhibiting all lipid utilization by the bacterium.
DC70459 GSK3011724A GSK 3011724A (DG-167, GSK-3011724A) is a potent, specific inhibitor of β-ketoacyl-ACP synthase (KasA, Kd=9 nM), shows anti-tubercular activity (MIC H37Rv=0.8 uM); shows much weaker apparent dissociation constant for both Pks10 and Pks (Kd=1.4 uM); inhibits mycolic acid biosynthesis and shows negligible activity against a panel of unrelated proteins and 18 Gram-positive and Gram-negative bacterial species.
DC70368 DU011 DU011 is a noncanonical anti-infective agent and small-molecule inhibitor of capsule biogenesis, targets MprA (Kd=30 nM), a MarR family transcriptional repressor of multidrug efflux pumps, inhibits capsule expression in E. coli. DU011 does not alter Escherichia coli antibiotic resistance and has significantly enhanced inhibition of capsule expression, compared with other proposed MprA ligands, such as salicylate and 2,4-dinitrophenol (DNP).
DC46502 Brilacidin Brilacidin (PMX 30063) is an anti-infective antimicrobial with MIC90s of 1 and 8 μg/mL for Gram-positive bacteria Streptococcus pneumonia and Streptococcus viridans, and MIC90 of 8 and 4 μg/mL for Gram-negative bacteria Haemophilus influenza and Pseudomonas aeruginosa. Brilacidin is a defensin mimetic antibiotic compound.
DC46373 TP0586532 TP0586532 is a non-hydroxamate LpxC inhibitor (IC50=0.101 μM). TP0586532 as a compound with a low cardiovascular risk that is effective against K. pneumoniae, including resistant strains.
DC44112 2',3'-Dideoxy-5-iodocytidine 2',3'-Dideoxy-5-iodocytidine is used for gene sequencing can be used as an antibiotic. 2',3'-Dideoxy-5-iodocytidine is particular effective against Mycobacterium.
