Etheno adducts: from tRNA modifications to DNA adducts and …
2021年6月16日 · Early studies with the carcinogen vinyl chloride revealed that these modified bases were being formed in DNA and RNA and might be responsible for mutations and cancer. The etheno bases are also derived from other carcinogenic vinyl monomers.
crytic/etheno: Simplify Ethereum security analysis and testing - GitHub
Etheno is the Ethereum testing Swiss Army knife. It’s a JSON RPC multiplexer, analysis tool wrapper, and test integration tool. It eliminates the complexity of setting up analysis tools like Echidna on large, multi-contract projects. If you are a smart contract developer, you should use Etheno to test your contracts.

A Direct Chemical Repair of Etheno-Type RNA Damages - Wiley …
2024年11月26日 · The understanding and effective manipulation of etheno damages in RNA with chemical tools hold implications for deciphering their role in mutagenesis and RNA biology, potentially opening avenues for targeted therapeutic interventions and biomarker development.
Etheno DNA-base adducts from endogenous reactive species
1999年3月8日 · Promutagenic etheno (ε) adducts in DNA are generated through reactions of DNA bases with LPO products derived from endogenous sources or from exposure to several xenobiotics. The availability of sensitive methods has made it possible to detect three ε-adducts in vivo, namely εdA, εdC and N2,3-εdG.
Mechanism of 1,N2-Etheno-2′-deoxyguanosine Formation from ...
Background levels of etheno adducts have been attributed to the reaction of DNA with 2,3-epoxyaldehydes, a proposed product of lipid peroxidation. We have examined the reaction of (2R,3S)-epoxyhexanal with dGuo to give ...
Base-Modified Nucleosides: Etheno Derivatives - PMC
2016年4月28日 · This review presents synthesis and chemistry of nucleoside analogs, possessing an additional fused, heterocyclic ring of the “etheno” type, such as 1,N 6-ethenoadenosine, 1,N 4-ethenocytidine, 1,N 2-ethenoguanosine, and other related derivatives. Formation of ethenonucleosides, in the presence of α-halocarbonyl reagents and their mechanism ...
Etheno-adduct-forming chemicals: from mutagenicity testing to …
Ethenobases generate mainly base pair substitution mutations. With the advent of new techniques of molecular biology, mutations were investigated in the ras and p53 genes of tumors induced by vinyl chloride and urethane.
Etheno adducts: from tRNA modifications to DNA adducts and …
2021年6月16日 · Etheno (and ethano) derivatives of nucleic acid bases have an extra 5-membered ring attached. These were first noted as wyosine bases in tRNAs. Some were fluorescent, and the development of etheno derivatives of adenosine, cytosine, and guanosine led to the synthesis of fluorescent analogs of ATP, NAD+, and other cofactors for use in ...
Repair of etheno DNA adduct damage is done primarily by glycosylases and also by the direct action of dioxygenases. Some human DNA polymerases (η, ) can insert bases opposite etheno adducts in DNA κ and RNA, and the reverse transcriptase activity may be of relevance with the RNA etheno adducts.
