Jervine (11-Ketocyclopamine) is a naturally occuring steroidal alkaloid is derived from the Veratrum plant species. Jervine is a teratogen implicated in birth defects when consumed by animals during a certain period of their gestation. Over the Hedgehog signaling pathway Jervine effectively inhibit the tumor growth using three human tumor xenograft models including lung cancer, pancreatic cancer and basal cell carcinoma. Jervine has the potential to advance to a treatment for different tumors.

Ombitasvir (ABT-267) is an antiviral drug for the treatment of hepatitis C virus (HCV) infection. Ombitasvir is a potent inhibitor of the hepatitis C virus protein NS5A, has favorable pharmacokinetic characteristics and is active in the picomolar range against genotype 1 - 6. In 2015, it was approved by FDA for use in combination with paritaprevir, ritonavir and dasabuvir in the product Viekira Pak for the treatment of HCV genotype 1.

Ergonovine (also known as ergometrine) is the active water soluble component of ergot of rye. Ergonovine is being used as a maleate salt to prevent or treate postpartum haemorrhage and postabortion haemorrhage. Ergonovine stimulates alpha-adrenergic and serotonin receptors, thus activating contractions of uterine and vascular smooth muscle. Ergonovine may have depressant effect on CNS system as it binds to dopamine receptors.

Glycyrrhizic Acid is specific compound isolated from licorice plants. Ammonium Glycyrrhizate (also known as GLYCYRRHIZIN, AMMONIATED) is a salt, was investigated to be a safe and is used as ingredient in the formulation of makeup, fragrance, hair care, skin care, shaving, personal hygiene and suntan products.

Cevadine, veratridine, and related lipophilic ceveratrum alkaloids cause activation of the voltage-sensitive Na+ channels of nerve, heart, and skeletal muscle cell membranes similar to pyrethrins. Both veratridine and cevadine alter the ion selectivity of Na+ channels and cause persistent activation. The receptor for these alkaloids has not been isolated, but experiments indicate it is distinct from that of pyrethrin. Structurally, veratridine and cevadine differ only in their acyl group. Cevadine has been used as an insecticide, acting as a paralytic agent with higher toxicity to insects than to mammals. It has been used to study Na+ channel blockers such as vincamine and vincanol by inducing Na+ channels in the presence and absence of the drugs being tested.

QS-21 is a purified soapbark tree (Quillaja saponaria) extract that enhances the ability of the immune system to respond to vaccine antigens. QS-21 is a promising adjuvant candidate for use in humans due to the ease of purification, its improved safety profile, and its ability to enhance cellular and humoral immunogenicity. The mechanism of action of QS-21 was speculated to be similar to QA, forming complexes with cholesterol that intercalate into the cell membrane lipids. This intercalation creates pores in the membrane to accelerate the uptake of a co-delivered antigen by the antigen presenting cells. Multiple clinical trials using QS-21 as an adjuvant, demonstrated satisfactory safety profiles and enhanced immunogenicity in immunocompromised volunteers

Dalbavancin is a mixture of five closely related active homologs (A0, A1, B0, B1, and B2); the component B0 is the major component of dalbavancin. The predominant component of dalbavancin is Factor B0, which accounts for >75% of the whole complex. Dalbavancin is a second-generation lipoglycopeptide antibiotic that was designed to improve on the natural glycopeptides currently available, such as vancomycin and teicoplanin. Modifications from these older glycoprotein classes allowed a similar mechanism of action with increased activity and once weekly dosing. Its use is indicated for the treatment of acute bacterial skin and skin structure infections (ABSSSI) caused by the following gram-positive microorganisms: Staphylococcus aureus (including methicillin-susceptible and methicillin-resistant strains), S. pyogenes, S. agalactiae, and S. anginosus group (including S. anginosus, S. intermedius, and S. constellatus). Under the brand name DALVANCE Dalbavancin is indicated for acute bacterial skin and skin structure infections (ABSSSI) caused by designated susceptible strains of Gram-positive microorganisms. The bactericidal action of dalbavancin results primarily from inhibition of cell-wall biosynthesis. Specifically, dalbavancin prevents incorporation of N-acetylmuramic acid (NAM)- and N-acetylglucosamine (NAG)-peptide subunits from being incorporated into the peptidoglycan matrix; which forms the major structural component of Gram-positive cell walls. The large hydrophilic molecule is able to form hydrogen bond interactions with the terminal D-alanyl-D-alanine moieties of the NAM/NAG-peptides, which is normally a five-point interaction. Binding of dalbavancin to the D-Ala-D-Ala prevents the incorporation of the NAM/NAG-peptide subunits into the peptidoglycan matrix. In addition, dalbavancin alters bacterial-cell-membrane permeability and RNA synthesis.

Norvancomycin is an analog of glycopeptide antibiotic vancomycin. It was first found to be produced by a soil microorganisms such Nocardia orientalis and Amycolatopsis orientalis and recently was found in actinomycete Amycolatopsis orientalis CPCC200066. Norvancomycin can be derived by demethylation at N-terminus of vancomycin. It has significant inhibitory activity against Gram-positive cocci and bacilli. The mode of action of norvancomycin is based on its ability to bind to the cell-wall peptidoglycan of Gram-positive bacteria terminating tripeptide -L-Lys-D-Ala-D-Ala. Similar to vancomycin in terms of antibacterial activity, spectrum and clinical efficacy norvancomycin has more potent antibiotic activity against Staphylococcus aureus and higher affinity for bacteria cell wall analogue DALAA than vancomycin. Norvancomycin has been widely used in China to treat endocarditis, osteomyelitis and other severe infections caused by Staphylococcus aureus (including methicillin-resistant strains). The adverse drug reactions of norvancomycin are like vancomycin, such as nephrotoxicity, ototoxicity, rash and itching. Norvancomycin is not available therapeutically outside of China.
