RNA Control by Photoreversible Acylation

External photocontrol over RNA function has emerged as a useful tool for studying nucleic acid biology. Most current methods rely on fully synthetic nucleic acids with photocaged nucleobases, limiting application to relatively short synthetic RNAs. Here we report a method to gain photocontrol over RNA by postsynthetic acylation of 2′-hydroxyls with photoprotecting groups. One-step introduction of these groups efficiently blocks hybridization, which is restored after light exposure. Polyacylation (termed cloaking) enables control over a hammerhead ribozyme, illustrating optical control of RNA catalytic function. Use of the new approach on a transcribed 237 nt RNA aptamer demonstrates the utility of this method to switch on RNA folding in a cellular context, and underlines the potential for application in biological studies.

The invention discloses a 2-indolone derivative with tyrosine kinase inhibition activity, geometric isomers and medicinal salts thereof, and a preparation method and an application of the above compounds. Tyrosine kinase inhibition activity evaluation confirms that the derivative is a compound with good tyrosine kinase activity, so the derivative has potential antitumor activity, and can be used to prepare tumor disease prevention and treatment medicines (antitumor medicines) as an active component. The derivative provides research and enforcement foundation for tumor treatment, and has a wide application prospect.
