Socio-demographical Profile of 7285 SARS-Cov-2 Positive Early Cases; Comparison with National Four Epidemic Waves.

Objectives were to investigate aspects of the COVID-19 epidemics via testing the individuals who were referred to Aramesh Medical Laboratory in Tehran and to integrate the molecular results with epidemiological data since the beginning of the epidemic. In this cross-sectional Study 77528 outpatients were referred to Aramesh Medical laboratory by physicians for the diagnosis of SARS-CoV-2 infection between March 2019 and May 2021. Viral acid nucleic extracted from nasal and throat specimens and subsequently amplified using Reverse Transcriptase Real-Time PCR.

A Review of the Phytochemistry and Antimicrobial Properties of L. and Subspecies.

L. () is an important medicinal herb of the family Lamiaceae. In the current study, we explained the critical evaluation of traditional uses, the phytochemistry and the antimicrobial properties of and its subspecies, with a focus on the mechanisms of actions of the most important phytochemicals from subspecies.

Histone Deacetylase Inhibitory and Cytotoxic Activities of the Constituents from the Roots of .

Four prenylated flavonoids, including isosophoranone, sophoraflavanone G, alopecurone J, alopecurone P, and a resveratrol derivative HPD (2-(4-hydroxyphenyl)-2,3-dihydrobenzo[b] furan-3,4,6-triol), were isolated from the roots of . The cytotoxic activity of obtained compounds was evaluated against A2780, A549, HeLa, and HCT116 human cancer cell lines. We also evaluated their histone deacetylase (HDAC) inhibitory activities.

Effects of phytochemicals on macrophage cholesterol efflux capacity: Impact on atherosclerosis.

High-density lipoprotein cholesterol (HDL) is the major promoter of reverse cholesterol transport and efflux of excess cellular cholesterol. The functions of HDL, such as cholesterol efflux, are associated with cardiovascular disease rather than HDL levels. We have reviewed the evidence base on the major classes of phytochemicals, including polyphenols, alkaloids, carotenoids, phytosterols, and fatty acids, and their effects on macrophage cholesterol efflux and its major pathways.

A qHNMR method for simultaneous quantification of terpenoids from Ferula ovina (Boiss.) Boiss roots.

Ferula ovina (Boiss.) Boiss is one of the most important endemic medicinal plants in Iran, which has three main terpenoid compounds including ferutinin, stylosin and tschimgine. Ferutinin is the strongest natural phytoestrogen that has agonistic activity on estrogen receptors, particularly α-receptors.

Histone deacetylase inhibitory and cytotoxic activities of the constituents from the roots of three species of .

Objectives: Histone deacetylase inhibitory and cytotoxic activities of 18 naturally occuring terpenoids (ferutinin, stylosin, tschimgine and guaiol), coumarins (umbelliprenin, farnesiferone B, conferone, feselol, ligupersin A, conferdione, conferoside) and sulfur-containing derivatives (latisulfies A-E, persicasulphides A and C) from the roots of three species of ( and ) were evaluated.

Materials And Methods: The cytotoxic activity of compounds was evaluated against human cancer cell lines (HeLa, HCT116, A2780 and A549) by AlamarBlue® assay using vorinostat as the positive control. On the other hand, we aimed to evaluate their inhibitory activities against pan-HDAC.

Absolute configuration and anti-cancer effect of prenylated flavonoids and flavonostilbenes from Sophora pachycarpa: Possible involvement of Wnt signaling pathway.

A new prenylated flavonostilbene, namely, alopecurone P together with three known compounds sophoraflavanone G, 2-(4-hydroxyphenyl)-2,3-dihydrobenzo[b]furan-3,4,6-triol and alopecurone J were characterized from the roots of Sophora pachycarpa. The absolute configuration of alopecurones J and P were characterized by comparison of experimental electronic circular dichroism (ECD) spectroscopy and simulated data using time-dependent density functional theory (TDDFT) for possible stereoisomers. The cytotoxic properties of isolated compounds have also been evaluated on two breast cancer cell lines (MCF-7 and MDA-MB-231) and normal cell line (NIH/3T3) using AlamarBlue®, flowcytometry and western blot assays.

Biologically active prenylated flavonoids from the genus Sophora and their structure-activity relationship-A review.

The genus Sophora (Fabaceae) has been used in traditional medicine for years. Prenylated flavonoids are one of the constituents of Sophora species that play important roles in their biological properties. Different classes of prenylated flavonoids are produced by Sophora spp.

Sulfur-containing compounds from the roots of Ferula latisecta and their cytotoxic activities.

Five new sulfur-containing compounds, with a new geometry (cis) of the propenyl moiety, and five known compounds were isolated from the roots of Ferula latisecta. The structures of these compounds, were elucidated on the basis of spectroscopic data including 1D and 2D NMR experiments and HRMS. All of the isolated compounds were tested against A2780, A549, HeLa, and HCT116 human cancer cell lines and some of them showed moderate cytotoxic activities.

Evaluation of phytochemicals, antioxidant and burn wound healing activities of Duchesne fruit peel.

Objectives: Cucurbita moschata Duchesne (pumpkin) is a well-known plant with several pharmacological effects. The aim of the present study was to assess burn wound healing activity of peel extract (CE). Also, standardized CE was assessed for antioxidant activity and antibacterial effects against major pathogens of burns.

Cytotoxic and apoptogenic properties of three isolated diterpenoids from Salvia chorassanica through bioassay-guided fractionation.

Bioassay-guided fractionation of Salvia chorassanica Bunge roots for the first time led to the isolation of taxodione, ferruginol and 6-hydroxysalvinolone. Cytotoxic studies revealed that all compounds exhibited high cytotoxic activity against apoptosis-proficient HL-60 and apoptosis-resistant K562 cells, with IC50 values ranging from 7.7 to 60.
