1. Peiminine (Raddeanine) is an effective inhibitor for lung inflammation and pulmonary fibrosis in a rat model of bleomycin-induced lung injury.

1. Peimine (Wanpeinine A) has good anti-inflammatory effects in vivo. 2. Peimine is an inhibitor to inhibit LPS-induced production of inflammatory cytokines by blocking the MAPKs and NF-κB signaling pathway.

Isoverticine exhibits significant antitussive, expectorant and anti-inflammatory activities, it also displays significant cytotoxicity.

1. Peimisine (Ebeiensine) can affect M-receptor, excit β-receptor, restrain the release of internal calcium, and promote to releaseing nitrogen monoxidum in order to relax tracheal smooth muscle and relieve asthma. 2. Peimisine can attenuate lung tissue injury( ALI), LDH and MDA amount in ALI mice in a dose dependent manner, it also lower the total protein, total white blood cells, lymphocyte and neutrophilic leukocyte in bronchoalveolar lavage fluid( BALF); suggests that peimisine can play a protective role against LPS-induced acute lung injury. 3. Peimisine has the protective effect on the experimental hepatic fibrosis formation, the possible mechanisms are associated with inhibiting fibrogenesis and fibrosis accumulation, and decreasing lipid peroxidation. 4. Peimisine can inhibit angiotensin I converting enzyme activity in a dose-dependent manner, displaying 5 % inhibitory concentration values of 526.5 microM, thus, it may have antihypertensive action.

Imperialine 3-β-D-glucoside (Sipeimine-3-beta-D-glucoside) is a natural product. Imperialine 3-β-D-glucoside may exhibit anti-tumor properties against multi-drug resistant tumor cells.

Peimisine 3-O-β-D-glucopyranoside is a steroidal alkaloid isolated from the bulb of Monocarpus monocarpus with partial neuroprotective activity, and can be used for the study of rotenone-induced neurotoxicity in the PC12 cell line.

Pingpeimine C Derived from Fritillaria sibiricum.

Pingpeimine B Derived from Fritillaria sibiricum.

Pingpeimine A has the effect of expectorating and lowering blood pressure. Derived from Fritillaria sibiricum.
