摘要:
Disclosed is a cucurbitane-triterpenoid compound for activating estrogen receptor activity, and a pharmaceutical composition, use and preparation method thereof. The cucurbitane-triterpenoid compound is presented as formula (I): wherein a single bond or a double bond is formed between C5 and C10, and a single bond or a double bond is fromed between C8 and C9; when a single bond is formed between C5 and C10, the R1 is oxygen; while a single bond is formed between C8 and C9, R2 is carbonyl group (—C═O), methyl hydroxyl group (—CH(OH)), methyl ketone or methyl dimethoxy group (—CH(OCH3)2); and wherein while R1 is oxygen (—O—) and R2 is carbonyl group (—C═O) or methyl hydroxyl group (—CH(OH)), a single bond is formed between R1 (—O—) and C19 of R2 such that R1 and R2 are formed tetrahydro-2H-pyran-2-one or hemiacetal ring.
摘要:
The present invention relates to compounds having estrogenic activity selected from the group consisting of Loliolide, (4S,6S)-4-Hydroxy-6-nonadecyl-tetrahydro-pyran-2-one, (4R,6S)-4-Hydroxy-6-nonadecyl-tetrahydro-pyran-2-one and analogues thereof. The compounds of the present invention are selective estrogen receptor modulator, which can selectively activate ERβ and simultaneously express high estrogenic activity, and also can be applied as medical or food compositions to improve estrogen deficiency-related symptoms.

Disclosed is a method for alleviating allergic asthma by using a bitter melon composition. The bitter melon composition comprises at least an effective amount of conjugated linolenic acid (CLN), wherein the bitter melon composition is administered to a subject suffering from allergic asthma to alleviate its symptoms. In the future, the bitter melon composition can be developed to as a health food, so as to prevent asthma, or alleviate the various symptoms of allergic asthma, such as airway hyperresponsiveness (AHR), airway inflammation, infiltration of inflammatory cell in lung tissue, or high level of serum IgE.
