Background: Emerging resistance of bacterial pathogens to clinically used drugs, including not only first-choice but also second- and third-choice drugs, is alarming, but since the 1990s only a modest number of new, first in class, drugs for systemic administration have been marketed for the treatment of bacterial infections. Objective: This article provides a review of recently reported new antibacterial chemotherapeutics app Read More

Background: Cancer is a leading cause of mortality in the world and metastasis is to blame. A number of naphthoquinones (NQs) have shown ability to reduce cancer stemness and metastatic potential. Furano-naphthoquinones (FNQs), which is a class of NQ characterized by the incorporation of an additional furan ring, have demonstrated improved anti-cancer potency as compared to the other classes of NQs. Objective: In this st Read More

Background: Metastasis is often derived from increased invasion and migration of tumor cells, and is the most frequent cause of cancer-associated death. Either the prophylactic or therapeutic treatment of metastatic cancer remains very challenging today by virtue of the complex histopathology and genetic or epigenetic variations. Medicinal scientists had discovered many potential anti-invasive and anti-metastatic Read More

The severe anticancer situation as well as the emergence of multidrug-resistant (MDR) cancer cells has created an urgent need for the development of novel anticancer drugs with different mechanisms of action. A large number of natural alkaloids, such as paclitaxel, vinblastine and camptothecin have already been successfully developed into chemotherapy agents. Following the success of these natural products, in t Read More

Background: Influenza viruses cause severe upper respiratory illness in children and the elderly during seasonal epidemics. Influenza viruses from zoonotic reservoirs can also cause pandemics with significant loss of life in all age groups. Although vaccination is one of the most effective methods to protect against seasonal epidemics, seasonal vaccines vary in efficacy, can be ineffective in the elderly population, and do n Read More

The main challenge of cancer treatment is multidrug resistance during chemotherapy. Cancer cell can evade cell death during every round of orthodox chemotherapy drugs, consequently being resistant after several rounds of standard drug treatment. One of the regimens to address this multidrug resistance problem is by drug combination. However, synthetic drugs always have problems of strong side effects and toxicity. Read More

Background: Despite of the globally positive trends in the epidemiology of tuberculosis, the increasing rates of drug-resistant strains are urging to introduce new antituberculars into clinical practice. Development of a new chemical entity from hit to marketed drug is an extremely time and resources consuming process with uncertain outcome. Repurposing of clinically used drugs can be a cheaper alternative to develop new Read More

Gaultheria, a genus belonging to the Ericaceae family, is typically a shrub that produces berries, and closely resembles the blueberry genus Vaccinium. Gaultheria species are used worldwide especially as food and medicine in China. Certain Gaultheria species are biologically active, as antioxidants, anti-inflammatories, and cytotoxic agents. Through literature searches and field surveys, the results of ethnobotanical uses Read More

Ebola virus has caused 26 outbreaks in 10 different countries since its identification in 1976, making it one of the deadliest emerging viral pathogens. The most recent outbreak in West Africa from 2014-16 was the deadliest yet and culminated in 11,310 deaths out of 28,616 confirmed cases. Currently, there are no FDA-approved therapeutics or vaccines to treat Ebola virus infections. The slow development of effective Read More

Inflammatory bowel disease (IBD) is an uncontrolled chronic inflammatory intestinal disorder, which requires medications for long-term therapy. Facing the challenges of severe side effects and drug resistance of conventional medications, to develop the strategies meet the stringent safety and effectiveness in the long-term treatment are urgent in the clinics. In this regard, a growing body of evidence confirms plant-sourced Read More

Numerous compounds with a benzothiazole scaffold that have been described in the literature show promising activities against several Gram-positive and Gramnegative bacteria, and also against Mycobacterium tuberculosis. Benzothiazole-based antibacterial compounds bind to different biological targets in bacterial cells and have been shown to be inhibitors of enzymes that are important for essential processes in the ba Read More
