New 2′-deoxyuridine derivatives containing long-chain hydrophilic substituents or hydrophilic groups at the 5 position of uracil were synthesized. 5-[4-(2-Carboxyethylcarbonylamino)-butyloxymethyl]-2′-deoxyuridine completely inhibits the growth of Mycobacterium tuberculosis at a concentration of 50 μg mL−1. However, oligo(ethylene glycol) derivatives do not exhibit activity even at high concentrations.

The site-selective functionalization of unactivated aliphatic amines is an attractive and challenging synthetic approach. We herein report a general strategy for the remote site-selective functionalization of unactivated C(sp3)–H bonds in amides by photogenerated amidyl radicals to form gem-difluoroalkenes with trifluoromethyl-substituted alkenes. The site selectivity is controlled by a 1,5-hydrogen
The invention provides a microRNA inhibitor that has two or more sequences complementary to the sequence of microRNA to be the target of inhibition, which two or more complementary sequences are linked via one or more linker residues.
