Monocrotaline is an 11-membered macrocyclic pyrrolizidine alkaloid extracted from the seeds of Crotalaria plants. It inhibits organic cation transporters OCT-1 and OCT-2, with IC50 values of 36.8 µM and 1.8 mM, respectively. Monocrotaline exhibits antitumor activity and shows certain cytotoxicity against liver cancer cells such as HepG2. It is also commonly used to induce pulmonary arterial hypertension models in rodents.

Yibeinoside A (Sinpeinine-3-O-β-glucoside) is an alkaloid from Fritillaria pallidiflora.

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

1. Sipeimine (Kashmirine) has antiasthmatic effect, on tracheal M receptor antagonist. 2. Sipeimine can make Kaba cholinergic induced contraction of tracheal strips of the dose-response curve to the right.

Regaloside A is a phenylpropane derived from lily of the valley that shows DPPH free radical scavenging activity at 160 ppm.Regaloside A has anti-inflammatory activity and antidepressant activity.

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.

Regaloside C, a glycerol glucoside isolated from the Lilium genus, exhibits notable anti-inflammatory properties.

Regaloside B, a phenylpropanoid isolated from Lilium longiflorum, exhibits anti-inflammatory activity by inhibiting the expression of iNOS (inducible nitric oxide synthase) and COX-2 (cyclooxygenase-2).

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.

Hupehenine is a steriodal alkaloid extracted from the bulbs of Fritillaria Hupehensis, with the potential for inhibiting acetylcholine, antagonism for muscarinic receptors and cholinesterase inhibition.

Kauran-16,17-diol, a natural diterpenoid product, exhibits anti-tumoral and apoptosis-inducing activities by inhibiting NO production in LPS-induced RAW 264.7 cells with an IC50 value of 17 μM.

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.

Regaloside F is a phenolic glyceroglucoside found in lily bulbs.

Galactose is a monosaccharide and hexose sugar widely present in most living cells, primarily absorbed into the bloodstream via SGLT1 and GLUT2 transporters and metabolised through the Leloir pathway. It inhibits alglucerase activity in monkey kidney CoS-1 cells, is a key component of cellular glycosylation, and plays a crucial role in neonatal neural development.

Pingpeimine C Derived from Fritillaria sibiricum.

Regaloside D is a natural product isolated from Lilium Longiflorum.

Pingpeimine B Derived from Fritillaria sibiricum.

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