RESUMO
BACKGROUND: Polypharmacology means drugs having interactions with multiple targets of a unique disease or many disease pathways. This concept has been greatly appreciated against complex diseases, such as oncology, CNS disorders, and anti-infectives. METHODS: The integration of diverse compounds available on public databases initiates polypharmacological drug discovery research. Immunocompromised patients may suffer from complex diseases. Multiple-component drug formulations may produce side effects and resistance issues due to unintended drug-target interactions. RESULTS: Polypharmacology remains a novel avenue to propose a more effective and less toxic treatment. The 4-amino quinoline scaffold has become an important construction motif for the development of new drugs against lifestyle diseases like cancer and infectious diseases like tuberculosis and malaria. CONCLUSION: The present study is an attempt to explore the polypharmacological effects of 4- aminoquinoline drugs to combat malaria, cancer, and tuberculosis.

Metacercariae of Clinostomum Leidy, 1856 are frequently encountered in freshwater fish. Clinostomum complanatum is a digenetic zoonotic parasite harbouring the intestine and body cavity of the fishes. 19 human incidences of Clinostomum complanatum infection have been reported to cause pharyngitis and lacramalitis from Japan, Thailand and Korea. Hence, adequate yet effective diagnosis is an issue. Designing primers used in the amplification of genes with adequate specificity and efficiency is of help in diagnosis. Hence, we describe primer design for cox-1 gene from the helminth parasite, Clinostomum complanatum parasitizing the intestine of fish Channastriata (Snakehead murrel). Thus, these designed primers set will be of further use in the wet lab for amplification of concerned gene or DNA fragment.
RESUMO
Thaparocleidus wallagonius is a monogenean parasite and a fish-borne pathogen with a worldwide distribution. The genome for Thaparocleidus wallagonius is known. Therefore, it is of interest to report the DNA motif analysis data in the 18S rDNA of Thaparocleidus wallagonius collected from the fish Wallago attu in India. This data forms a framework for an in-depth analysis of the parasite biology and development, immune evasion strategies, virulence and long-term survival within the definitive host.
RESUMO
BACKGROUND: Hepatitis C Virus (HCV) belongs to the Hepacivirus family. HCV has been designated as a very dreadful virus as it can attack the liver, causing inflammation and even may lead to cancer in chronic conditions. It was estimated that 71 million people around the world have chronic HCV infection. World Health Organization (WHO) reported that about 399000 people died because of chronic cirrhosis and liver cancer globally. In spite of the abundance of availability of drugs for the treatment of HCV, however, the issue of drug resistance surpasses all the possibilities of therapeutic management of HCV. Therefore, to address this issue of 'drug-resistance', various HCV targets were explored to quest the evaluation of the mechanism of the disease progression. METHODS: An attempt has been made in the present study to explore the various targets of HCV involved in the mechanism(s) of the disease initiation and progression and to focus on the mode of binding of ligands, which are co-crystallized at the active cavity of different HCV targets. CONCLUSION: The present study could predict some crucial features of these ligands, which possibly interacted with various amino acid residues responsible for their biological activity and molecular signaling pathway(s). Such binding mode may be considered as a template for the high throughput screening and designing of active congeneric ligands to combat HCV.
