Targeted Isolation of Anti-inflammatory Lignans from by Molecular Networking Approach.

Herein, the isolation of secondary metabolites from the aerial parts of guided by HPLC-MS and molecular networking analyses is reported. Twenty-two known compounds were dereplicated. Three new lignans (aequilabrines A-C (-)) and three known compounds (lariciresinol-4'-β-glucose (), roseoside (), and allantoin ()) were obtained.

Virtual Screening of Natural Products Database.

Constant research on natural products has generated, over time, a large number of compounds with the potential to be evaluated in several biological tests and subsequently have been cataloged in databases that allow other researchers to perform virtual screenings of activity in various biological systems. This considerably reduces the time for the development of new drugs. This review describes the main databases of natural products available for searching bioactive compounds.

Computer-Assisted Design of Thiophene-Indole Hybrids as Leishmanial Agents.

Background: Chemoinformatics has several applications in the field of drug design, helping to identify new compounds against a range of ailments. Among these are Leishmaniasis, effective treatments for which are currently limited.

Objective: To construct new indole 2-aminothiophene molecules using computational tools and to test their effectiveness against Leishmania amazonensis (sp.

Studies for Bacterystic Evaluation against of 2-Naphthoic Acid Analogues.

Background: Staphylococcus aureus is a gram-positive spherical bacterium commonly present in nasal fossae and in the skin of healthy people; however, in high quantities, it can lead to complications that compromise health. The pathologies involved include simple infections, such as folliculitis, acne, and delay in the process of wound healing, as well as serious infections in the CNS, meninges, lung, heart, and other areas.

Aim: This research aims to propose a series of molecules derived from 2-naphthoic acid as a bioactive in the fight against S.

Larvicidal Compounds Extracted from K. Schum (Sterculiaceae) Evaluated against L.

K. Schum (Sterculiaceae), a member of Malvaceae , is a Brazilian endemic plant that has been used by the indigenous tribe Pankarare as an insect repellent. A previous study has reported the isolation of terpenoids, flavonoids and pheophytins, in addition to the larvicidal activity of crude extracts derived from the aerial components (leaves, branches/twigs, and flowers).

Exploring Secondary Metabolites Database of Apocynaceae, Menispermaceae, and Annonaceae to Select Potential Anti-HCV Compounds.

Background: Hepatitis C is a disease that constitutes a serious global health problem, is often asymptomatic and difficult to diagnose and about 60-80% of infected patients develop chronic diseases over time. As there is no vaccine against hepatitis C virus (HCV), developing new cheap treatments is a big challenge.

Objective: The search for new drugs from natural products has been outstanding in recent years.
