Structural basis for repurpose and design of nucleoside drugs for treating COVID-19

SARS-CoV-2 has caused a global pandemic of COVID-19 that urgently needs an effective treatment. Nucleoside analog drugs including favipiravir have been repurposed for COVID-19 despite of unclear mechanism of their inhibition of the viral RNA polymerase (RdRp). Here we report the cryo-EM structures of the viral RdRp in complex with favipiravir and two other nucleoside inhibitor drugs ribavirin and penciclovir. Ribavirin and the ribosylated form of favipiravir share a similar ribose scaffold that is distinct from penciclovir. However, the structures reveal that all three inhibitors are covalently linked to the primer strand in a monophosphate form despite the different chemical scaffolds between favipiravir and penciclovir. Surprisingly, the base moieties of these inhibitors can form mismatched pairs with the template strand. Moreover, in view of the clinical disadvantages of remdesivir mainly associated with its prodrug form, we designed several orally-available remdesivir parent nucleoside derivatives, including VV16 that showed 5-fold more potent than remdesivir in inhibition of viral replication. Together, these results demonstrate an unexpected promiscuity of the viral RNA polymerase and provide a basis for repurpose and design of nucleotide analog drugs for COVID-19. One Sentence SummaryCryo-EM structures of the RNA polymerase of SARS-CoV-2 reveals the basis for repurposing of old nucleotide drugs to treat COVID-19.

Structural basis for repurposing a 100-years-old drug suramin for treating COVID-19

The COVID-19 pandemic by non-stop infections of SARS-CoV-2 has continued to ravage many countries worldwide. Here we report the discovery of suramin, a 100-year-old drug, as a potent inhibitor of the SARS-CoV-2 RNA dependent RNA polymerase (RdRp) through blocking the binding of RNA to the enzyme. In biochemical assays, suramin and its derivatives are at least 20-fold more potent than remdesivir, the currently approved nucleotide drug for COVID-19. The 2.6 [A] cryo-EM structure of the viral RdRp bound to suramin reveals two binding sites of suramin, with one site directly blocking the binding of the RNA template strand and the other site clash with the RNA primer strand near the RdRp catalytic active site, therefore inhibiting the viral RNA replication. Furthermore, suramin potently inhibits SARS-CoV-2 duplication in Vero E6 cells. These results provide a structural mechanism for the first non-nucleotide inhibitor of the SARS-CoV-2 RdRp and a rationale for repurposing suramin for treating COVID-19. One Sentence SummaryDiscovery and mechanism of suramin as potent SARS-CoV-2 RNA polymerase inhibitor and its repurposing for treating COVID-19.

Analysis of basic medical insurance and disease burden of the disabled people under the background of health poverty alleviation / 公共卫生与预防医学

Objective To explore the problems of health poverty faced by a special group of people with disabilities and the difficulties in the practice of health poverty alleviation, so as to provide a scientific basis for the health poverty alleviation of the disabled. Methods A self-made questionnaire was used for one-to-one survey, and a database was established by Excel. SPSS was used for descriptive analysis and horizontal comparison. Results The participation rate of basic medical insurance for the disabled was relatively high (93.40%), and the medical insurance payment was mainly paid by individuals (70.13%). The satisfaction of medical insurance was low (43.12%), and 84.64% of the disabled thought that their medical expenses were high. 45.22% of the families of disabled patients met the universal standard of catastrophic health expenditure. Compared with Shandong Province, the basic medical insurance coverage rate of the disabled in Hubei Province was slightly lower, the satisfaction rate of medical insurance was higher, and the proportion of catastrophic health expenditure of families was larger. The analysis of the results showed that the disabled people with a lower disability level, children and middle-aged with disabilities, the disabled people with less or more family members, and the disabled people without the minimum living subsistence allowances were not satisfied with the medical insurance. Conclusion The basic medical insurance in the two places has alleviated the difficulty of medical treatment for the disabled to a certain extent, but the family burden of diseases of the disabled was still heavy. The level of medical security for people with disabilities should be improved, and their economic burden of disease should be reduced, so as to improve the satisfaction of medical insurance.

An extract of Artemisia dracunculus L. stimulates insulin secretion from ß cells, activates AMPK and suppresses inflammation.

ETHNOPHARMACOLOGICAL RELEVANCE: Artemisia dracunculus L. (Russian tarragon) is a perennial herb belonging to the family Compositae and has a history of medicinal use in humans, particularly for treatment of diabetes. AIM OF THE STUDY: In this study a defined plant extract from A. dracunculus L. (termed PMI-5011) is used to improve beta(ß) cells function and maintain ß cell number in pancreatic islets as an alternative drug approach for successful treatment of diabetes. MATERIALS AND METHODS: Mouse and human pancreatic beta cells were treated with defined plant extract of A. dracunculus L. (PMI-5011) to understand the mechanism(s) that influence beta cell function and ß cell number. RESULTS: We found that the PMI-5011 enhances insulin release from primary ß cells, isolated mouse and human islets and it maintains ß cell number. Insulin released by PMI-5011 is associated with the activation of AMP-activated protein kinase (AMPK), and protein kinase B (PKB). Furthermore, PMI-5011 suppresses LPS/INFγ-induced inflammation and inflammatory mediator(s) in macrophages. PMI-5011 inhibited Nitric oxide (NO) production and expression of inducible nitric oxide synthase (iNOS) at the protein level and also attenuated pro-inflammatory cytokine (IL-6) production in macrophages. CONCLUSION: PMI-5011 has potential therapeutic value for diabetes treatment via increasing insulin release from ß cells and decreases capacity of macrophages to combat inflammation.
