Efficacy and safety of molnupiravir for COVID-19 patients was written by Fatima, Maurish;Azeem, Saleha;Saeed, Junaid;Shahid, Abia;Cheema, Huzaifa Ahmad. And the article was included in European Journal of Internal Medicine in 2022.Computed Properties of C13H19N3O7 The following contents are mentioned in the article:

Our study include the inability to investigate more subgroups as we used study level data instead of individual patient data, and the unavailability of the results of two trials which may result in publication bias. We conducted this meta-anal. to increase the statistical power of the available evidence by combining it and evaluating the safety and efficacy of molnupiravir for the treatment of COVID-19 patients. It may be speculated that molnupiravir may only be effective in some subgroups of hospitalized patients; therefore, publication of the results of these trials might help in investigating this. In conclusion, our study supports the use of molnupiravir in non- hospitalized patients with COVID-19. Further research should be focused on evaluating its comparative efficacy in relation to other available treatments. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate (cas: 2492423-29-5Computed Properties of C13H19N3O7).

Tetrahydrofuran (THF), or oxolane, is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent. Commercial tetrahydrofuran contains substantial water that must be removed for sensitive operations, e.g. those involving organometallic compounds. Although tetrahydrofuran is traditionally dried by distillation from an aggressive desiccant, molecular sieves are superior.Computed Properties of C13H19N3O7

Nucleoside analogs are reagents that resemble the structure of natural nucleosides and are widely applied in antiviral and anticancer therapy. Molnupiravir, a recently reported nucleoside analog drug, has shown its inhibitory effect against SARS-CoV-2. Rapid tracing of molnupiravir and its metabolites is important in the evaluation its pharmacol. effect, but direct sensing of molnupiravir as a single mol. has not been reported to date. Here, we demonstrate a nanopore-based sensor with which direct sensing of molnupiravir and its two major metabolites β-D-N4-hydroxycytidine and its triphosphate can be achieved simultaneously. In conjunction with a custom machine learning algorithm, an accuracy of 92% was achieved. This sensing strategy may be useful in the current pandemic and is in principle suitable for other nucleoside analog drugs. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate (cas: 2492423-29-5Quality Control of ((2R,3S,4R,5R)-3,4-Dihydroxy-5-((Z)-4-(hydroxyimino)-2-oxo-3,4-dihydropyrimidin-1(2H)-yl)tetrahydrofuran-2-yl)methyl isobutyrate).

Inhibition of Chikungunya virus by an adenosine analog targeting the SAM-dependent nsP1 methyltransferase was written by Mudgal, Rajat;Mahajan, Supreeti;Tomar, Shailly. And the article was included in FEBS Letters in 2020.Synthetic Route of C11H13IN4O4 The following contents are mentioned in the article:

Alphaviruses, including Chikungunya (CHIKV) and Venezuelan equine encephalitis virus (VEEV), are among the leading causes of recurrent epidemics all over the world. Alphaviral nonstructural protein 1 (nsP1) orchestrates the capping of nascent viral RNA via its S-adenosyl methionine-dependent N-7-methyltransferase (MTase) and guanylyltransferase activities. We developed and validated a novel capillary electrophoresis (CE)-based assay for measuring the MTase activity of purified VEEV and CHIKV nsP1. We employed the assay to assess the MTase inhibition efficiency of a few adenosine analogs and identified 5-iodotubercidin (5-IT) as an inhibitor of nsP1. The antiviral potency of 5-IT was evaluated in vitro using a combination of cell-based assays, which suggest that 5-IT is efficacious against CHIKV in cell culture (EC₅₀: 0.409μM).

Molnupiravir (MK-4482) is an investigational antiviral agent that is under development for the treatment of COVID-19. Given the potential high demand and urgency for this compound, it was critical to develop a short and sustainable synthesis from simple raw materials that would minimize the time needed to manufacture and supply molnupiravir. The route reported here is enabled through the invention of a novel biocatalytic cascade featuring an engineered ribosyl-1-kinase and uridine phosphorylase. These engineered enzymes were deployed with a pyruvate-oxidase-enabled phosphate recycling strategy. Compared to the initial route, this synthesis of molnupiravir is 70% shorter and approx. 7-fold higher yielding. Looking forward, the biocatalytic approach to molnupiravir outlined here is anticipated to have broad applications for streamlining the synthesis of nucleosides in general.

Haspin is a serine/threonine kinase that phosphorylates Thr-3 of histone H3 in mitosis that has emerged as a possible cancer therapeutic target. High throughput screening of approx. 140,000 compounds identified the β-carbolines harmine and harmol as moderately potent haspin kinase inhibitors. Based on information obtained from a structure-activity relationship study previously conducted for an acridine series of haspin inhibitors in conjunction with in silico docking using a recently disclosed crystal structure of the kinase, harmine analogs were designed that resulted in significantly increased haspin kinase inhibitory potency. The harmine derivatives also demonstrated less activity towards DYRK2 compared to the acridine series. In vitro mouse liver microsome stability and kinase profiling of a representative member of the harmine series (42, LDN-211898) are also presented. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (cas: 24386-93-4Safety of (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol).

Slowly on, Slowly off: Bisubstrate-Analogue Conjugates of 5-Iodotubercidin and Histone H3 Peptide Targeting Protein Kinase Haspin was written by Kestav, Katrin;Viht, Kaido;Konovalov, Anton;Enkvist, Erki;Uri, Asko;Lavogina, Darja. And the article was included in ChemBioChem in 2017.Electric Literature of C11H13IN4O4 The following contents are mentioned in the article:

The atypical protein kinase haspin is a key player in mitosis by catalyzing the phosphorylation of Thr3 in histone H3, and thus ensuring the normal function of the chromosomal passenger complex. Here, we report the development of bisubstrate-analog inhibitors targeting haspin. The compounds were constructed by linking 5-iodotubercidin to the N terminus of histone H3 peptide. The new conjugates show high affinity (sub-nanomolar K_D) towards haspin as well as slow kinetics of association and dissociation (residence time of several hours). This reflects a unique binding mode and translated into improved selectivity. The latter was confirmed in a biochem. binding/displacement assay with a panel of ten protein kinases, in a thermal shift assay with off-targets of 5-iodotubercidin (adenosine kinase and the Cdc2-like kinase family) and in assay with spiked HeLa cell lysate. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (cas: 24386-93-4Electric Literature of C11H13IN4O4).

Bioorthogonally Functionalized NAD⁺ Analogues for In-Cell Visualization of Poly(ADP-Ribose) Formation was written by Wallrodt, Sarah;Buntz, Annette;Wang, Yan;Zumbusch, Andreas;Marx, Andreas. And the article was included in Angewandte Chemie, International Edition in 2016.Application of 24386-93-4 The following contents are mentioned in the article:

Poly(ADP-ribos)ylation (PARylation) is a major posttranslational modification and signaling event in most eukaryotes. Fundamental processes like DNA repair and transcription are coordinated by this transient polymer and its binding to proteins. ADP-ribosyltransferases (ARTs) build complex ADP-ribose chains from NAD⁺ onto various acceptor proteins. Mol. studies of PARylation thus remain challenging. Herein, we present the development of bioorthogonally functionalized NAD⁺ analogs for the imaging of PARylation in vitro and in cells. Our results show that 2-modified NAD⁺ analogs perform remarkably well and can be applied to the in-cell visualization of PARylation simultaneously in two colors. This tool gives insight into the substrate scope of ARTs and will help to further elucidate the biol. role of PARylation by offering fast optical, multichannel read-outs.
