Dichapetalins are a small class of triterpenoid compounds found primarily in the Dichapetalaceae family but also reportedly in Phyllanthus (Euphorbiaceae). [1] They are structural derivatives of dammarene characterized by a C6C2 unit connected to a dammarene or a 13,30-cyclodammarane skeleton with variable C-17 side chains containing actone, spirolactone, lactol, acetal, or furan moieties. They have been found to display cytotoxicity against several cancer cell lines. [2]
Incarvillea is a genus of about 16 species of flowering plants in the family Bignoniaceae, native to central and eastern Asia, with most of the species growing at high altitudes in the Himalaya and Tibet. The most familiar species is Incarvillea delavayi, a garden plant commonly known as hardy gloxinia or Chinese trumpet flower. Unlike most other members of Bignoniaceae, which are mainly tropical woody plants, species of Incarvillea are herbs from temperate regions.
Gouania lupuloides, known as chewstick or whiteroot, is a neotropical plant of the family Rhamnaceae. It is occasionally used as a teeth cleaning implement.
Flindersia pimenteliana is a species of plant in the family Rutaceae. It may be known by the common name Maple Silkwood. The common name Maple Silkwood may also refer to Flindersia australis, Flindersia brayleyana or Flindersia pubescens. It is found in Queensland (Australia), West Papua (Indonesia), and Papua New Guinea. It is threatened by habitat loss.
Goniothalamus cheliensis is a species of plant in the Annonaceae family. It is native to China and Thailand. Bioactive molecules isolated from its roots have been reported to have cytotoxic activity in tests with cultured human cancer cells.
Physalis coztomatl is a plant species in the genus Physalis. It produces edible orange-yellow fruits, but is rarely cultivated. The leaves are oval-shaped. It is native to South America; the Aztecs used it medicinally. It contains labdane diterpenes, and was the first species in Physalis in which they were found.
Eletefine is an isoquinoline alkaloid first isolated in 1998 from Cissampelos glaberrima. It is one of few known compounds containing the so-called stephaoxocane skeleton, alongside stephaoxocanidine, excentricine, and the stephalonganines.
Psorospermum febrifugum is a flowering plant species in the genus Psorospermum occurring in Zimbabwe and Mozambique. It grows in open woodland over a wide range of altitudes. The inconspicuous flowers are fragrant, creamy-white and some 8mm in diameter. The fruit is a small berry some 6mm in diameter and bright red when mature.
Cucurbitane is a chemical compound with formula C
30H
54. It is a polycyclic hydrocarbon, specifically a triterpene. It is an isomer of lanostane, from which it differs by the formal shift of a methyl group from the 10 to the 9β position in the standard steroid numbering scheme.
Aurantiomides are quinazoline alkaloids isolated from the fungus Penicillium aurantiogriseum.
Isooncodine is an anticholinergic alkaloid. It was first synthesized in 1989 because it is an isomer of oncodine, an azafluorenone alkaloid derived from Meiogyne monosperma. It was first derived from the leaves of Polyalthia longifolia.
14-Norpseurotin A is an alkaloid and a bio-active metabolite of Aspergillus, featuring an oxa-spiro-lactam core.
Iochroma fuchsioides is an Iochroma species found in Ecuador and Colombia. It was first described in 1848. In addition to the known withanolide D {1}, three new withanolides have been isolated from Iochroma fuchsioides.
Bacopasides are triterpene saponins isolated from Bacopa monnieri.
Ergostane is a tetracyclic triterpene, also known as 24S-methylcholestane. The compound itself has no known uses; however various functionalized analogues are produced by plants and animals. The most important of these are the heavily derivatised withanolides. However simpler forms do exist, such as the sterane campestane(24R-methylcholestane). Along with cholestane and stigmastane, this sterane is used as a biomarker for early eukaryotes.
Coniella is a fungus genus in the family Schizoparmeaceae. This genus Coniella are reported as a typical plant pathogenic fungi for grape, eucalyptus and several plant. It mainly found in Europe, Asian, also South Africa. less report in American, only one paper published new spaces founded. In the chemical constitution study, two paper reported azaphilone are the main metabolites.
Penicillium paneum is a species of fungus in the genus Penicillium which can spoil cereal grains. Penicillium paneum produces 1-Octen-3-ol and penipanoid A, penipanoid B, penipanoid C, patulin and roquefortine C
The xenortides (A-D) are a class of linear peptides isolated from the bacterium Xenorhabdus nematophila, a symbiont of the entomopathogenic nematode Steinernema carpocapsae. This class of compounds is known for their insect virulence and cytotoxic biological activities. The tryptamide containing compounds show higher biological activity than the phenylethylamides. The most biologically active compound was found to be xenortide B with a potency of less than 1.6 μM activity against Trypanosoma brucei rhodesiense and Plasmodium falciparum (malaria), however it is also the most toxic to mammalian cells which limits its viability as a treatment.
Incarvillateine is a complex monoterpene alkaloid that is a derivative of α-truxillic acid. It can be isolated from the plant genus Incarvillea.
Incarvillea sinensis is a species of the genus Incarvillea.
Mitrephora glabra is a species of plant in the family Annonaceae. It is native to Borneo. Rudolph Scheffer, the Dutch botanist who first formally described the species, named it after its smooth leaves. Bioactive compounds isolated from its bark have been reported to have antifungal activity in tests with Aspergillus niger.
