Usage

Description

1,2-Bismaleimidoethane (BMOE) is a homobifunctional, maleimide crosslinking reagent that is used for conjugation between sulfhydryl groups (-SH). It is an off-white solid and is commonly utilized to explore and characterize protein structure, such as oligomerization, and protein interactions. The reactivity of BMOE is similar to other maleimide crosslinkers like BMB and BMH, but it differs in length. This difference in length can help determine intraand intermolecular distances in protein oligomers or interactions.

Highly potent and stable capped siRNAs with picomolar activity for RNA interference

Put a cap on it: Hairpin-shaped RNAs and dumbbell-shaped RNAs were prepared using a thiol-maleimino Michael addition and exhibited good serum and thermal stability. These capped structures were shown to be cleaved by Dicer and RNA interference (RNAi) experiments showed that RhpRNA (see picture, top right) was highly efficient at RNAi with an IC50 value of 6 pM.

Cp?Co(III)-Catalyzed C-H Alkylation with Maleimides Using Weakly Coordinating Carbonyl Directing Groups

A novel protocol for ortho-C-H alkylation of aromatic and heteroaromatic ketones and esters under Cp?Co(III) catalysis has been developed for the first time. The reaction proceeds through initial cyclometalation via weak chelation-assisted C-H bond activation, followed by coordination of activated alkene, insertion between Co-C, and protodemetalation.
