Bioactivity-guided fractionation of the methanolic root bark extract of Leucophyllum frutescens led to the identification of leubethanol (1), a new serrulatane-type diterpene with activity against both multi-drug-resistant and drug-sensitive strains of virulent Mycobacterium tuberculosis.
Serrulatane diterpenoids are natural products found in plants from a subset of genera within the figwort family (Scrophulariaceae). Many of these compounds have been characterized as having antimicrobial properties and share a common diterpene backbone. One example, leubethanol from Texas sage
Bioassay-guided fractionation of the minor active fractions obtained from the root bark of Leucophyllumfrutescens (Berl.) I. M. Johnst. led to isolation from the n-hexane extract of a new compound with moderate activity against the H37Rv Mycobacterium tuberculosis strain (MIC 63 microg/mL), and low
The aim of the present study was to evaluate the potential antimicrobial activity of 14 plants used in northeast México for the treatment of respiratory diseases, against drug-sensitive and drug-resistant strains of Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae type b and
