Ivanova, Larisa published the artcile1,3-Thiazolbenzamide Derivatives as Chikungunya Virus nsP2 Protease Inhibitors, COA of Formula: C12H9N3O5S, the main research area is antiviral thiazolbenzamide derivative Chikungunya virus onstructural protein protease inhibitor.

Chikungunya fever results from an infection with Chikungunya virus (CHIKV, genus Alphavirus) that is prevalent in tropical regions and is spreading fast to temperate climates with documented outbreaks in Europe and the Americas. Currently, there are no available vaccines or antiviral drugs for prevention or treatment of Chikungunya fever. The nonstructural proteins (nsPs) of CHIKV responsible for virus replication are promising targets for the development of new antivirals. This study was attempted to find out new potential inhibitors of CHIKV nsP2 protease using the ligand-based drug design. Two compounds 10 and 10c, identified by mol. docking, showed antiviral activity against CHIKV with IC50 of 13.1 and 8.3μM, resp. Both compounds demonstrated the ability to inhibit the activity of nsP2 in a cell-free assay, and the impact of compound 10 on virus replication was confirmed by western blot. The mol. dynamics study of the interactions of compounds 10 and 10c with CHIKV nsP2 showed that a possible mechanism of action of these compounds is the blocking of the active site and the catalytic dyad of nsP2.

Barrett, Jeffrey S. published the artcileRisk assessment of therapeutic agents under consideration to treat COVID-19 in paediatric patients and pregnant women, Computed Properties of 55981-09-4, the main research area is drug repurposing vaccine child pregnancy COVID19 risk assessment; Clinical pharmacology; Infectious diseases; Paediatrics.

Aim : Repurposing strategies to address the COVID-19 pandemic have been accelerated. As both pregnant and paediatric patients are likely to be excluded from most planned investigations, the list of repurposed options and the available data on these drugs and vaccines provide a baseline risk assessment and identify gaps for targeted investigation. Methods : Clin. trials have been searched and reviewed; 23 repurposed drugs and drug combinations and nine candidate vaccines have been assessed regarding the availability of relevant data in paediatrics and pregnant women and to evaluate expected or unanticipated risk. Results : Thirteen of the repurposed drugs or drug combinations are indicated for use in paediatrics in some age category albeit for indications other than COVID-19; 10 of these are indicated for use in pregnant women. Even in cases where these drugs are indicated in the populations, source data from which safety and or dosing could be extrapolated for use in COVID-19 is sparse. Vaccine trials are ongoing and generally exclude pregnant women; only in a few instances have paediatric subgroups been planned for enrolment. Data from individual case studies and RWD may suggest that subpopulations of both paediatric patients and pregnant women may be more at risk, particularly those in an increased inflammatory state. Conclusion : In conjunction with more prospective collaboration, plans are evolving to ensure that we will be better prepared to address similar situations especially in paediatrics and pregnant women where experience is limited and actual practice relies heavily on leveraging data from other populations and indications.

Hossain, Jamal Md. published the artcileRepurposing therapeutic agents against SARS-CoV-2 infection: most promising and neoteric progress, HPLC of Formula: 55981-09-4, the main research area is review public health crisis palliative care repurposing strategy pandemic; SARS covid clin trial review; SARS-CoV-2; clinical trials; covid-19 pandemic; palliative care; public health crisis; repurposing strategy.

The pathogenic and highly transmissible etiol. agent, SARS-CoV-2, has caused a serious threat COVID-19 pandemic. WHO has declared the epidemic a public health emergency of international concern owing to its high contagiosity, mortality rate, and morbidity. Till now, there is no approved vaccine or drug to combat the COVID-19 and avert this global crisis. Areas covered In this narrative review, we summarized the updated results (Jan. to August 2020) of the most promising repurposing therapeutic candidates to treat the SARS-CoV-2 viral infection. The repurposed drugs classified under four headlines like antivirals, anti-parasitic, immune-modulating, and miscellaneous drugs were discussed with their in vitro efficacy to recent clin. advancements against COVID-19. Expert opinion Currently, palliative care, ranging from outpatient management to intensive care, including oxygen administration, ventilator support, i.v. fluids therapy, with some repurposed drugs, are the primary weapons to fight against COVID-19. Until a safe and effective vaccine is developed, an evidence-based drug repurposing strategy might be the wisest option to save people from this catastrophe. Several existing drugs are now under clin. trials, and some of them are approved in different places of the world for emergency use or as adjuvant therapy in COVID-19 with standard of care.

Simsek Yavuz, Serap published the artcileAn update of anti-viral treatment of COVID-19, Category: esters-buliding-blocks, the main research area is review COVID19 RNA antiviral remdesivir merimepodib hydroxychloroquine; antiviral; treatment; SARS-CoV-2; COVID-19.

Currently there is not an effective antiviral treatment for COVID-19, but a large number of drugs have been evaluated since the beginning of the pandemic, and many of them have been used for the treatment of COVID-19 despite the preliminary or conflicting results of the clin. trials. We aimed to review and summarize all of the current knowledge on the antivirals for COVID-19. There are 2 main drug groups for SARS-CoV-2: agents that target proteins or RNA of the virus or interfere with proteins or biol. processes in the host that support the virus. The main drug groups include inhibitors of viral entry into the human cell (convalescent plasma, monoclonal antibodies, nanobodies, mini proteins, human soluble ACE-2, camostat, dutasteride, proxalutamide, bromhexin, hydroxychloroquine, umifenovir nitazoxanid, niclosamide, lactoferrin), inhibitors of viral proteases (lopinavir/ritonavir, PF-07321332, PF-07304814, GC376), inhibitors of viral RNA (remdesivir, favipiravir, molnupiravir, AT-527, merimepodib, PTC299), inhibitors of host proteins supporting virus (plitidepsin, fluvoxamine, ivermectin), and agents supporting host natural immunity (Interferons). When taking into account the results of all the available laboratory and clin. trials on the subject, monoclonal antibodies seem to be the most effective treatment for COVID-19 at the moment, and high-titer convalescent plasma also could be effective when administered during the early phase of the disease. As lopinavir/ritonavir, hydroxychloroquine, merimepodib, and umifenovir were found to be ineffective in RCTs, they should not be used. Addnl. studies are needed to define the role of remdesivir, favipiravir, interferons, ivermectin, dutasteride, proxulutamide, fluvoxamine, bromhexine, nitazoxanide, and niclosamid in the treatment of COVID-19. Finally, the results of phase trials are waited to learn whether or not the newer agents such as molnupiravir, PF-07321332, PF-07304814, plitidepsin and AT-527 are effective in the treatment of COVID-19.

Pang, Wenwen published the artcileAnticancer activities of Zanthoxylum bungeanum seed oil on malignant melanoma, COA of Formula: C13H18O3, the main research area is Zanthoxylum malignant melanoma seed oil anticancer; Cell cycle arrest; Invasion; Malignant melanoma; Seed oil Apoptosis; Zanthoxylum bungeanum.

Zanthoxylum bungeanum Maxim. (ZBM), a Chinese herb medicine and food additive, has been shown to have broad-spectrum beneficial effects. However, the anticancer activities of its seed have not been reported.for the first time investigated the anti-proliferation activity of seed oil of ZBM (ZBSO) on melanoma A375 cells as well as the underlying mechanisms. The chem. composition of ZBSO was analyzed by Ultra Performance Liquid Chromatog. A375 cells exposure at different concentrations of ZBSO to examine the selectivity vs. normal skin cells, invasion, apoptosis and cell cycle arrest. Furthermore, transcriptome anal. was employed to investigate potential anticancer mechanisms of ZBSO. Major compounds of ZBSO were identified and unsaturated fatty acid made up the major compound ZBSO-treated A375 cells showed more typical apoptotic morphol. features than normal cells. ZBSO can significantly inhibit invasion and proliferation of A375 cells by G1 phase arrest and induction of apoptosis. Transcriptome anal. showed that ZBSO may affect cell cycle and MAPK signaling pathway of A375 cells. ZBSO possessed anticancer activities that were selectively effective to A375 cells. This study support the hypothesis that ZBSO is a capable candidate for anti-melanoma agent, and provide new insights for future work on investigating the utilization of ZBSO in malignant melanoma treatment.

Abeesh, Prathapan published the artcilePreparation and characterization of beta sitosterol encapsulated nanoliposomal formulation for improved delivery to cancer cells and evaluation of its anti-tumor activities against Daltons Lymphoma Ascites tumor models, Application of 2′,7′-Dichloro-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-3′,6′-diyl diacetate, the main research area is beta sitosterol nanoliposome lymphoma cell apoptosis tumor mitigation.

Beta sitosterol (BS) is a dietary phytosterol with promising therapeutic applications. The low bioavailability and rapid degradation of BS is the main challenges for their use in the food and pharmaceutical industries. Liposome mediated drug delivery systems are the useful approaches to improve the biopharmaceutical properties of BS. In this study, we had prepared nanoliposome encapsulated beta sitosterol (LBS) with improved bioavailability and stability. The prepared nanoliposomes had spherical vesicles, with mean particle size of 114.5 nm and had an encapsulation efficiency of 86%. Our in vitro study results showed that LBS treatment could induce apoptosis in lymphoma cell lines as evidenced by acridine orange/ethidium bromide and nuclear staining. Our in vivo studies involving exptl. tumor models revealed that LBS treatment could significantly (p < 0.01) reduce the tumor loads, improve the survival rate, and stabilize the body weights in Dalton's Lymphoma Ascites (DLA) tumor bearing mice when compared to BS. Hematol. and serum biochem. parameters also improved significantly (p < 0.01) after LBS administration than free drug. The overall study results revealed that LBS exhibits promising therapeutic efficacy in comparison with non-encapsulated BS in regulating exptl. tumor development as well as induction of lymphoma cell apoptosis.

Nguyen, Duc Ba published the artcileApplication of plasma jet to the inhibition of the proliferation of hepatic malignant cells via reactive oxygen species generation, Safety of 2′,7′-Dichloro-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-3′,6′-diyl diacetate, the main research area is hepatic malignant cell proliferation dielec barrier plasma jet discharge.

In vitro treatment of hepatic malignant cells with plasma-activated medium conjugated with gemcitabine was investigated with a He plasma jet generated by a two-ring dielec. barrier discharge (DBD) reactor. The DBD reactor was operated by high-voltage pulses of alternating polarity (frequency: 20 kHz; pulse width: 4 us). The electron d. of plasma plume was estimated to be 9×1012 to 10×1012 cm-3, and the jet temperature was around 36°C. The plasma jet exhibited the inhibitory effects on the growth of hepatic malignant cells via the generation of reactive oxygen species, which could be potentially applicative in anticancer therapies. The optimization of the operating parameters and configuration of the plasma jet would help increase the possibility in practical cancer treatments.
