Background: Coronavirus disease-2019 (COVID-19) was declared a "pandemic" by the World Health Organization (WHO) in early March 2020. Globally, extraordinary measures are being adopted to combat the formidable spread of the ongoing outbreak. Under such conditions, people's adherence to preventive measures is greatly affected by their awareness of the disease. Aim: This study was aimed to assess the level of awareness and preparedness to fight against COVID-19 among the healthcare workers (HCWs) and other residents of the SouthWest Saudi Arabia. Methods: A community-based, cross-sectional survey was conducted using a self-developed structured questionnaire that was randomly distributed online among HCWs and other residents (age ≥ 12 years) of SouthWest Saudi Arabia for feedback. The collected data were analyzed using Stata 15 statistical software. Results: Among 1,000 participants, 36.7% were HCWs, 53.9% were female, and 44.1% were aged ≥ 30 years. Majority of respondents showed awareness of COVID-19 (98.7%) as a deadly, contagious, and life-threatening disease (99.6%) that is transmitted through human-to-human contact (97.7%). They were familiar with the associated symptoms and common causes of COVID-19. Health organizations were chosen as the most reliable source of information by majority of the participants (89.6%). Hand hygiene (92.7%) and social distancing (92.3%) were the most common preventive measures taken by respondents that were followed by avoiding traveling (86.9%) to an infected area or country and wearing face masks (86.5%). Significant proportions of HCWs (P < 0.05) and more educated participants (P < 0.05) showed considerable knowledge of the disease, and all respondents displayed good preparedness for the prevention and control of COVID-19. Age, gender, and area were non-significant predictors of COVID-19 awareness. Tripathi et al. Awareness and Preparedness About COVID-19 Outbreak Conclusion: As the global threat of COVID-19 continues to emerge, it is critical to improve the awareness and preparedness of the targeted community members, especially the less educated ones. Educational interventions are urgently needed to reach the targeted residents beyond borders and further measures are warranted. The outcome of this study highlighted a growing need for the adoption of innovative local strategies to improve awareness in general population related to COVID-19 and its preventative practices in order to meet its elimination goals.
The virus severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) is currently affecting more than 200 countries and territories worldwide. It has been declared as pandemic by World Health Organization (WHO) and the whole world is suffering from corona virus disease 2019 . Currently, no treatment for SARS-CoV-2 are approved because of lack of evidence, but a number of clinical trials are in process and we are expecting fruitful results very soon. This review focuses on various approaches of treatment and few of the most recent clinical trials carried out in this field.
Thiazolidinediones are a class of well-established antidiabetic drugs, also named as glitazones. Thiazolidinedione structure has been an important structural domain of research, involving design and development of new drugs for the treatment of type 2 diabetes. Extensive research on the mechanism of action and the structural requirements has revealed that the intended antidiabetic activity in type 2 diabetes is due to their agonistic effect on peroxisome proliferator-activated receptor (PPAR) belonging to the nuclear receptor super family. Glitazones have specific affinity to PPARγ, one of the subtypes of PPARs. Certain compounds under development have dual PPARα/γ agonistic activity which might be beneficial in obesity and diabetic cardiomyopathy. Interesting array of hybrid compounds of thiazolidinedione PPARγ agonists exhibited therapeutic potential beyond antidiabetic activity. Pharmacology and chemistry of thiazolidinediones as PPARγ agonists and the potential of newer analogues as dual agonists of PPARs and other emerging targets for the therapy of type 2 diabetes are presented. This review highlights the possible modifications of the structural components in the general frame work of thiazolidinediones with respect to their binding efficacy, potency, and selectivity which would guide the future research in design of novel thiazolidinedione derivatives for the management of type 2 diabetes.
Plants have been extensively studied since ancient times and numerous important chemical constituents with tremendous therapeutic potential are identified. Attacks of microorganisms including viruses and bacteria can be counteracted with an efficient immune system and therefore, stimulation of body’s defense mechanism against infections has been proven to be an effective approach. Polysaccharides, terpenoids, flavonoids, alkaloids, glycosides, and lactones are the important phytochemicals, reported to be primarily responsible for immunomodulation activity of the plants. These phytochemicals may act as lead molecules for the development of safe and effective immunomodulators as potential remedies for the prevention and cure of viral diseases. Natural products are known to primarily modulate the immune system in nonspecific ways. A number of plant-based principles have been identified and isolated with potential immunomodulation activity which justify their use in traditional folklore medicine and can form the basis of further specified research. The aim of the current review is to describe and highlight the immunomodulation potential of certain plants along with their bioactive chemical constituents. Relevant literatures of recent years were searched from commonly employed scientific databases on the basis of their ethnopharmacological use. Most of the plants displaying considerable immunomodulation activity are summarized along with their possible mechanisms. These discussions shall hopefully elicit the attention of researchers and encourage further studies on these plant-based immunomodulation products as potential therapy for the management of infectious diseases, including viral ones such as COVID-19.
Salvadora persica L. (Salvadoraceae) is an evergreen shrub growing in the Middle East, Africa, and Southern Asia. It is traditionally known as “miswak” and used as toothbrushes and for the treatment of toothache, gum diseases, boils, chest infection, gonorrhea, headache, spleen troubles, stomachache, and ulcers. To the best of our knowledge, this is the first study aimed at conducting phytochemical, cytotoxic, and antimicrobial investigations of the fruits (berries) of S. persica collected from the Jazan region of Saudi Arabia. Analysis of the ethanol extract of S. persica fruits using GC-MS showed the presence of six esters (20.71%), seven alkanes (15.47%), tetracosamethyl-cyclododecasiloxane (9.91%), eicosamethyl-cyclodecasiloxane (7.27%), and 1-monolinoleoylglycerol (5.17%). The predominant constituents were acetyl dasycarpidan-1-methanol (10.47%), tetracosamethyl-cyclododecasiloxane (9.91%), eicosamethyl-cyclodecasiloxane (7.27%), and 1-monolinoleoylglycerol (5.17%). The petroleum ether extract of the fruits contained mainly eicosamethyl-cyclodecasiloxane (23.81%), 1-monolinoleoylglycerol (11.78%), (Z,Z,Z)-9,12,15-octadecatrienoic acid ethyl ester derivative (10.56%), and tetracosamethyl-cyclododecasiloxane (9.91%). The cytotoxic properties of the ethanol extract were investigated by MTT assay against the breast MCF7, ovary A2780, and colon HT29 cells. The fruit extract of S. persica was selective against the ovarian and colon cancer cells compared to normal fibroblast cells (MRC5) as it showed IC50 values 17.50, 8.35, and 5.12, against MCF7, A2780, and HT29 cells, respectively. Interestingly, the fruit extract was also found to possess selective antimicrobial activity for Streptococcus mutans isolates with minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of 3.12 and 6.25 mg/mL, respectively. Interestingly, it was found to be ineffective against other Gram-positive as well as Gram-negative microorganisms. This study provides insight into the bioactive components present in the fruits of the plant that can be utilized for its cytotoxic and antimicrobial properties.
In recent years, indole derivatives have acquired conspicuous significance due to their wide spectrum of biological activities. The anticonvulsant drug design is based on the presumption (1) that for the activity in maximal electroshock seizure (MES) evaluation, at least one phenyl or similar aromatic group in close proximity to a two electron donor atom is required. For activity in pentylenetetrazole (PTZ) evaluation, an alkyl group close to a two electron donor atom is needed.Several five-membered aromatic systems such as triazoles, oxadiazoles and thiadiazoles having three heteroatoms at symmetrical positions have been evaluated for their anticonvulsant activity (2, 3). New 3-aryl/alkylimino-indol-2-ones were synthesized and screened for their anticonvulsant and anti-inflammatory activities. Compounds having 1-naphthyl and 4-chlorophenyl substituents were most potent compounds of the series (4). A series of 3-aryl/alkylimino-indol-2-ones were synthesized and screened for anti- A series of new 5-(1H-indol-3-yl)methyl-4-(substituted aryl)-2,4-dihydro-3H-1,2,4-triazole-3-thiones (4a-g), 5-(1H--indol-3-yl)methyl-N-(substituted aryl)-1,3,4-oxadiazol--2-amines (5a-g) and 5-(1H-indol-3-yl)methyl-N-(substituted aryl)-1,3,4-thiadiazol-2-amines (6a-g) were prepared by treating 2-(1H-indol-3-yl)acetyl-N-(substituted phenyl)hydrazine carbothioamides (3a-g) with suitable reagents. All the newly synthesized compounds were screened for their anticonvulsant activity in the MES model and were compared with the standard drugs phenytoin sodium and carbamazepine. Out of the twenty-one compounds studied, 4b, 4e, 4f, 5b, 5d, 5g, 6b, 6d and 6e showed comparable MES activity to phenytoin and carbamazepine after 0.5 h. Compound 5b showed to be more potent than carbamazepine after 4 h. Compounds 4a, 4c, 4d, 5a, 5c, 5e, 5f, 6f and 6g showed lower neurotoxicity than phenytoin.
