WebPreviously, the bile salt analog CaPA (an aniline-substituted cholic acid) was shown to block spore germination and protect rodents from CDI caused by multiple C. difficile strains and isolates. In this study, we found that CaPA is an alternative substrate inhibitor of C. difficile spore germination. By competing with taurocholate for binding ... WebBecause of their high nucleophilic reactivity, aniline and phenol undergo substitution reactions with iodine, a halogen that is normally unreactive with benzene derivatives. The mixed halogen iodine chloride (ICl) provides a more electrophilic iodine moiety, and is effective in iodinating aromatic rings having less powerful activating substituents. WebIn case of aniline due to conjugation the lone pair density is less than that of methylamine. Due to this reason, aniline is less basic than methylamine. Why aniline is basic while Acetanilide is not? Basicity is the ability of a compound to donate lone pair. The lone pair in both aniline and acetanilide are delocalized due to resonance. east rand mall doctor
