We have explored the reaction mechanism of the metal-free B(C6 F5 )3 -catalysed hydrogenation of carbonyl compounds to the corresponding secondary alcohols by density functional theory calculations. Possible reaction routes have been investigated in detail and the results provide solid support for the mechanism proposed on the basis of experimental(More)
Ribosomal proteins (RPs) are indispensable in ribosome biogenesis and protein synthesis, and play a crucial role in diverse developmental processes. Our previous studies on Ribosomal Protein Large subunit (RPL) genes provided insights into their stress responsive roles in rice. In the present study, we have explored the developmental and stress regulated(More)
Intercalation by threading is anticipated to feature in DNA-binding molecules for developing DNA-targeted diagnostics and therapeutics. We investigated the role of an imidazolyl moiety in threading intercalators of DNA by employing a number of imidazolyl-naphthalenediimide conjugates. Threading intercalation was studied by UV spectroscopy, competitive(More)
Silylene-S-thione [PhC(NtBu)2Si(═S)N(SiMe3)2] (2) and silylene-Se-selone [PhC(NtBu)2Si(═Se)N(SiMe3)2] (3) compounds were prepared from the silylene [PhC(NtBu)2SiN(SiMe3)2] (1) with 1 equiv of 1/8 S8 and 1 equiv of Se powder, respectively, in high yields. Furthermore, compounds 2 and 3 reacted with CuCl and CuBr and yielded [{PhC(NtBu)2}Si(═S→CuX)N(SiMe3)2](More)
In molecular biology, understanding the functional and structural aspects of DNA requires sequence-specific DNA binding probes. Especially, sequence-specific fluorescence probes offer the advantage of real-time monitoring of the conformational and structural reorganization of DNA in living cells. Herein, we designed a new class of D2A(More)
