Provided herein are novel irreversible sialidase inhibitors. These compounds can be conjugated with a detectable tagging moiety such as azide-annexed biotin via CuAAC for isolation and identification of sialidases. The provided compounds and the corresponding detectable conjugates are useful for detecting sialidase-containing pathogens and imaging in situ sialidase activities under physiological conditions.

A method of treating cancer comprises administering: (a) a therapeutically effective amount of a compound of Formula (I) or a pharmaceutically acceptable salt thereof; and (b) a therapeutically effective amount of an additional anti-cancer agent, to a subject in need of such treatment, the compound of Formula (I) being: where X, R1, R2, ring A, L1, L2, L3, and R5 are as defined in this disclosure.
dilithium biphenyl (Li2C12H10) with alkyl fluorides has been studied from the point of view of the distribution of products. Two main reaction pathways, the nucleophilic substitution (SN2) and the electron transfer (ET), can compete to yield the same alkylation products in what is known as the SN2–ET dichotomy. SN2 seems to be the main mechanism operating with primary alkyl fluorides (n-RF). Alkylation proceeds
从产物分布的观点出发,已经研究了二锂联苯基(Li 2 C 12 H 10)与烷基氟化物的反应。两种主要的反应途径,亲核取代(S N 2)和电子转移(ET),可以竞争产生相同的烷基化产物,即所谓的S N 2–ET二分法。S N 2似乎是与伯烷基氟化物(n -RF)相互作用的主要机理。烷基化反应的收率很高,所得的烷基化二氢联苯阴离子(n -RC 12 H 10 Li)可以用第二种常规亲电试剂(E +),得到了合成上令人感兴趣的脱芳香化联苯衍生物(n -RC 12 H 10 E)。随着我们向仲(s -RF)和叔烷基氟化物(t -RF)的转移,反应产生了更多的ET产物,在这种情况下,该机理似乎主要由ET主导。在这种情况下,烷基化通过自由基偶合仍然可行,从而获得合成吨-RC 12 ħ 10 E,虽然在较低的产率。对这个S N的合理解释基于将5-己烯基氟化物和1,1-二甲基-5-己烯基氟化物用作与Li

The present disclosure features a strain-promoted [2+2+2] reaction that can be carried out under physiological conditions. In general, the reaction involves reacting a pi-electrophile with a low lying LUMO with a quadricyclane on a biomolecule, generating a covalently modified biomolecule. The selectivity of the reaction and its compatibility with aqueous environments provides for its application in vivo and in vitro. The reaction is compatible with modification of living cells. In certain embodiments, the pi-electrophile can comprise a molecule of interest that is desired for delivery to a quadricyclane-containing biomolecule via [2+2+2] reaction.
