A mild, simple, and controllable metal-free photocatalytic system for the transformation of arylmethyl bromides to corresponding alcohols and aldehydes in high yields with visible-light irradiation has been achieved. Eosin Y was found to be an efficient promoter for this oxidative dehalogenation reaction under photo irradiation conditions.

The invention relates to antibiotic compounds of formula (A1) and pharmaceutically acceptable salts, solvates, tautomers and combinations thereof, wherein X and L are optional linkers and one of RA or R1 comprises Ar1, wherein Ar1 is an antibiotic resistance breaker moiety which comprises an optionally substituted C6-10 aryl, C7-13 aralkyl, C5-10 heteroaryl, C6-13 heteroaralkyl, C5-10 heterocyclyl, C6-13 heterocyclalkyl, C3-10 carbocyclyl, C4-13 carbocyclalkyl, -C(=NR')-NR'R'' or –CH2- CH=CH2 group; wherein after administration of the compound to a bacterial infection this moiety reduces or prevents efflux. The invention also discloses pharmaceutical compositions comprising compounds of formula (A1) and the use of such compounds as medicaments, in particular, to treat bacterial infections, such as drug-resistant bacterial infections.
D and E Rings May Not Be Indispensable for Antofine: Discovery of Phenanthrene and Alkylamine Chain Containing Antofine Derivatives as Novel Antiviral Agents against Tobacco Mosaic Virus (TMV) Based on Interaction of Antofine and TMV RNA

(TMV) RNA, a series of phenanthrene and alkylamine chain containing antofine derivatives 1–41 were designed, synthesized, and systematically evaluated for their antiviral activity against TMV. The results showed that most of these compounds exhibited good to excellent anti-TMV activity, which indicated that the D and E rings of antofine may not be indispensable. Phenanthrene is important for these
