ABSTRACT: The title compound, C(15)H(20)O(3), a sesquiterpene lactone, was isolated from the aerial parts of Carpesium minus Hemsl. (Compositae). The mol-ecule is composed of three rings, with the two cyclo-hexane rings in chair conformations and the cyclo-pentane ring adopting a twist conformation. The A/B ring junction is trans-fused. The absolute configuration shown has been arbitrarily assigned. In the crystal, mol-ecules are linked into [100] chains by O-H?O hydrogen bonds.

Propargylaminyl 3?-hy-droxy-11-oxo-18?-olean-12-en-29-oate.

Project description:The title compound, C(33)H(49)NO(3), is the propargyl-amide of 18?-glycyrrhetinic acid, a penta-cyclic triterpenoid of inter-est as a therapeutic agent. The five six-membered rings of the glycyrrhetinic acid moiety show normal geometries, with four rings in chair conformations and the unsaturated ring C in a half-chair conformation. In the crystal, the terminal N-propargylcarboxamide group has remarkable structural effects on weak hydrogen-bond-like inter-actions. Particularly noteworthy are an inter-molecular O-H?? inter-action accepted side-on by the terminal alkyne group [O?C = 3.097?(2) and 3.356?(2)?Å] and a short inter-molecular C-H?O inter-action [C?O = 3.115?(2)?Å] donated by the alkyne C-H group. An N-H?O [N?O = 3.251?(2)?Å] and a C(alkyl)-H?O [C?O = 3.254?(2)?Å] interaction complement the crystal structure.

2?-Hydroxyeudesma-4,11(13)-Dien-8?,12-Olide Isolated from Inula britannica Induces Apoptosis in Diffuse Large B-cell Lymphoma Cells.

Project description:2?-Hydroxyeudesma-4,11(13)-dien-8?,12-olide (HEDO), a eudesmane-type sesquiterpene lactone belonging to large group of plant terpenoids isolated from Inula britannica, displays cytotoxic activity against diffuse large B cell lymphoma cells in vitro. However, the molecular mechanism of the anticancer effect remains unclear. In this study, we showed that HEDO inhibits cell growth by inducing apoptosis in lymphoma cell lines through its antiproliferative activity. HEDO increases the depolarization of mitochondrial membrane potential and upregulated intracellular reactive oxygen species (ROS). Furthermore, we examined the cell cycle effect, and our results provided evidence that the arrest of the cell cycle at the SubG0/G1 phase plays an important role in the ability of HEDO to inhibit cell growth in Ontario Cancer Institute (OCI)-LY3 lymphoma cells by preventing nuclear factor-kappa B (NF-?B) signaling. In addition, HEDO induced apoptosis by instigating the activation of Bcl-2-associated X (BAX) and cleaved caspase-3, decreasing B-cell lymphoma 2 (BCL2), B-cell lymphoma-extra large (BCL-XL), and procaspase 3 expression levels. Based on these findings, we suggest that HEDO has potential as an anticancer drug of lymphoma by inducing ROS-dependent accumulation of SubG0/G1 arrest and apoptosis in OCI-LY3 cells.

(3R,4S,5S,8S,10R,13R)-3-Hy-droxy-kaura-9(11),16-dien-18-oic acid.

Project description:The title compound, C(20)H(28)O(3), was isolated during our investigation into the chemical composition and pharmacological activity of Centipeda cunninghamii (DC.) A. Braun & Asch. (Asteraceae). The enanti-opure compound, a diterpene with a carbon skeleton, is composed of three six- and one five-membered rings in chair, twist-boat, half-chair and envelope conformations, respectively. Each mol-ecule makes one intra- and one inter-molecular O-H?O hydrogen bond in the crystal lattice, forming hydrogen-bonded chains along [010]. The absolute configuration of the compound was assigned on the basis of optical rotation measurements.

3α-Hy-droxy-tirucalla-8,24-dien-21-oic acid.

Project description:The title compound, C(30)H(48)O(3), a triterpene isolated from the resin of canarium schweinfurthiiand, is an isomer of the previously reported triterpene 3α-hy-droxy-tirucalla-7,24-dien-21-oic acid [Mora et al. (2001 ▶). Acta Cryst. C57, 638-640], which crystallizes in the same trigonal space group. The title mol-ecule consists of four fused rings having chair, half-chair, half-chair and envelope conformations for rings A, B, C and D, respectively (steroid labelling). An intra-molecular C-H⋯O hydrogen bond generates an S(7) ring. In the crystal, mol-ecules are linked by O-H⋯O and C-H⋯O inter-actions, forming (001) sheets.

12-Anilinomethyl-9?-hy-droxy-4,8-dimethyl-3,14-dioxatricyclo-[9.3.0.0]tetra-dec-7-en-13-one.

Project description:The title compound, C(21)H(27)NO(4), was synthesized from 9?-hy-droxy-parthenolide, which was isolated from the chloro-form extract of the aerial parts of Anvillea radiata. The asymmetric unit contains two independent mol-ecules. In each, the ten-membered ring displays an approximative chair-chair conformation. Each of the five-membered rings adopts a flattened envelope conformation, the C(H)-C-C(H) atoms representing the flap lie out of the mean plane through the remaining four atoms by 0.443?(2) and 0.553?(2)?Å. The dihedral angle between the least-squares planes through the ten- and five-membered rings in the two mol-ecules are similar [22.54?(17) and 23.39?(14)°]. In the crystal, mol-ecules are linked by O-H?O, O-H?N and N-H?O hydrogen bonds.

12?-Hy-droxy-3,27-dioxooleanano-28,13-lactone.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C(30)H(44)O(5). They comprise a triterpenoid skeleton of five six-membered rings and a five-membered lactone ring. The five six-membered rings are all trans-fused. In both independent mol-ecules the D rings adopt a slightly distorted half-chair conformation due the presence of the lactone ring while the other four six-membered rings all adopt chair conformations. The characteristic carbon-carbon double bond of the oleanoic skeleton is absent. Inter-molecular O-H?O hydrogen bonds between the hy-droxy and carbonyl groups occur in the crystal structure.
