Cytotoxic Constituents from Hyptis verticillata

Journal of Natural Products, 1993
A new cytotoxic (P-388 ED50 4 microgm/ml) arylnaphthalene lignan has been isolated from the Mexican medicinal plant Hyptis verticillata (Lamiaceae) and characterized as 5-methoxydehydropodophyllotoxin [1]. Eight additional lignans were also obtained by bioactivity-directed fractionation using the brine shrimp lethality test.

Abietane Diterpenes from Hyptis suaveolens

Chemistry & Biodiversity, 2013
AbstractInvestigation of the constituents of the whole plant of Hyptis suaveolens led to the isolation of three new abietane diterpenes, isosuaveolic acid (1), 8α,9α‐epoxysuaveolic acid (2), and 14‐O‐methylsuaveolic acid (3), together with eleven known compounds. The structures of 1–3 were established by spectroscopic methods and chemical correlations.

Tumor-Inhibitory Agent from Hyptis emoryi (Labiatae)

Journal of Pharmaceutical Sciences, 1972
The extract of Hyptis emoryi (Labiatae) has shown tumor-inhibiting properties in the 5WA16 test system of the Cancer Chemotherapy National Service Center. By means of melting point, mixed melting point, IR, mass spectrometry, elemental analysis, and preparation of derivatives, the agent responsible for this action was shown to be betulinic acid.
