Abstract: S-Adenosyl-L-methionine (SAM) analogs are adaptable tools for studying and therapeutically inhibiting SAM-dependent methyltransferases (MTases). Some MTases play significant roles in host-pathogen interactions, one of which is Clostridioides difficile-specific DNA adenine MTase (CamA). CamA is needed for efficient sporulation and alters persistence in the colon. To discover potent and selective CamA inhibitors, we explored modifications of the solvent-exposed edge of the SAM adenosine moiety. Starting from the two parental compounds (6e and 7), we designed an adenosine analog (11a) carrying a 3-phenylpropyl moiety at the adenine N6-amino group, and a 3-(cyclohexylmethyl guanidine)-Et moiety at the sulfur atom off the ribose ring. Compound 11a (IC50 = 0.15 μM) is 10x and 5x more potent against CamA than 6e and 7, resp. The structure of the CamA-DNA-inhibitor complex revealed that 11a adopts a U-shaped conformation, with the two branches folded toward each other, and the aliphatic and aromatic rings at the two ends interacting with one another. 11a occupies the entire hydrophobic surface (apparently unique to CamA) next to the adenosine binding site. Our work presents a hybrid knowledge-based and fragment-based approach to generating CamA inhibitors that would be chem. agents to examine the mechanism(s) of action and therapeutic potentials of CamA in C. difficile infection.

YieldReaction ConditionsOperation in experiment
In dichloromethane; at 20℃; for 18h; Under a nitrogen atmosphere, cyclohexylmethylamine (40.9 ML, 315 mmol) was added dropwise to a solution of <strong>[723280-98-6]7-bromo-4-chloro-3-nitroquinoline</strong> (30.0 g, 105 mmol) in dichloromethane (524 mL). The reaction was stirred for 18 hours at ambient temperature and then concentrated under reduced pressure. Water (200 mL) was added to the residue, and the mixture was stirred for three hours. Acetonitrile was added; a precipitate formed. The solid was isolated by filtration, dried under a flow of air for two hours, and recrystallized from acetonitrile to provide 24.0 g of (7-bromo-3-nitroquinolin-4- yl) cyclohexylmethylamine as a yellow solid.

It is disclosed herein that the display of side chains identified as activein galanin or those of the nonpeptide galanin receptor agonist galnon on arigid platform creates a compound capable of recognition by the receptorGalR1. Mixtures of 3 to 4 amines were coupled to the triacid platform (D. Mink,et al., Tetrahedron Lett, (1998) 39, 5709-5712; G. Haberhauer, et al.,Tetrahedron Lett, (2000) 41, 5013-5016; and L. Somogyi, et al., Tetrahedron,(2001) 57, 1699-1708) and obtained small combinatorial libraries. Activemixtures were obtained (after deblocking with trifluoroacetic acid) from theamines shown: cyclohexylmethyl amine, 2; fluorenyl amine 3 ande-t-BOC-/-lysine methyl ester 4. This mixture (11 compounds) was fractionatedby HPLC and the most active compound (structure 5, Galmic, or itscyclodiastereomer) was identified by mass spectrometry. The individualmolecule was prepared by total synthesis which will be described elsewhere.
