Herbgenomics meets Papaveraceae: a promising -omics perspective on medicinal plant research.

Herbal medicines were widely used in ancient and modern societies as remedies for human ailments. Notably, the Papaveraceae family includes well-known species, such as Papaver somniferum and Chelidonium majus, which possess medicinal properties due to their latex content. Latex-bearing plants are a rich source of diverse bioactive compounds, with applications ranging from narcotics to analgesics and relaxants.

The Activity of L. Latex and Its Components on HPV Reveal Insights into the Antiviral Molecular Mechanism.

Yellow-orange latex of L. has been used in folk medicine as a therapeutic agent against warts and other visible symptoms of human papillomavirus (HPV) infections for centuries. The observed antiviral and antitumor properties of latex are often attributed to alkaloids contained therein, but recent studies indicate that latex proteins may also play an important role in its pharmacological activities.

Combined Protein and Alkaloid Research of Latex Reveals CmMLP1 Accompanied by Alkaloids with Cytotoxic Potential to Human Cervical Carcinoma Cells.

L. is a latex-bearing plant used in traditional folk medicine to treat human papillomavirus (HPV)-caused warts, papillae, and condylomas. Its latex and extracts are rich in many low-molecular compounds and proteins, but there is little or no information on their potential interaction.

Characterization and expression of a novel thaumatin-like protein (CcTLP1) from papaveraceous plant Corydalis cava.

Thaumatin-like proteins (TLPs, osmotins) form a protein family which shares a significant sequence homology to the sweet-tasting thaumatin from the plant Thaumatococcus daniellii. TLPs are not sweet-tasting and are involved in response to biotic stresses and developmental processes. Recently it has been shown using a proteomic approach that the tuber extract from Corydalis cava (Papaveraceae) contains a TLP protein.

[Antiviral compounds isolated from plants].

Viruses are intracellular pathogens which utilize a number of host metabolic processes for virus replication in addition to proteins which are encoded for virus itself. Therefore, an effective antiviral drug must interfere with virus encoded proteins without affecting any cellular metabolic processes. Unfortunately, many antiviral drugs that have an inhibitory effect on virus replication, also have an inhibitory effect on molecular processes in infected, as well as uninfected, cells.

Protoberberine compounds extracted from Chelidonium majus L. as novel natural photosensitizers for cancer therapy.

Background: It has been shown that secondary metabolites occur in Chelidonium majus L. (C. majus) crude extract and milky sap (alkaloids such as berberine, coptisine, chelidonine, chelerythrine, sanguinarine, and protopine) are biologically active compounds with a wide spectrum of pharmacological functions.

Which Plant Proteins Are Involved in Antiviral Defense? Review on In Vivo and In Vitro Activities of Selected Plant Proteins against Viruses.

Plants have evolved a variety of defense mechanisms to tackle virus attack. Endogenous plant proteins can function as virus suppressors. Different types of proteins mediate defense responses against plant viruses.

Isolation and characterization of a non-specific lipid transfer protein from Chelidonium majus L. latex.

Plant non-specific lipid transfer proteins (nsLTPs) are small basic proteins, which mostly play a role in intracellular lipid transport and antimicrobial defense. Recently it was shown using shotgun proteomic approach that the whole plant extract of Chelidonium majus L. (Papaveraceae) contains relatively abundant nsLTPs.

Proteomic comparison of Chelidonium majus L. latex in different phases of plant development.

Chelidonium majus L. (Papaveraceae) latex is used in traditinonal folk medicine to treat papillae, warts, condylomas, which are visible effects of human papilloma virus (HPV) infections. The aim of this work was to provide new insights into the biology and medicinal use of C.

Viral and other cell-penetrating peptides as vectors of therapeutic agents in medicine.

Efficient delivery of heterologous molecules for treatment of cells is a great challenge in modern medicine and pharmacology. Cell-penetrating peptides (CPPs) may improve efficient delivery of a wide range of macromolecular cargos, including plasmid DNA, small interfering RNA, drugs, nanoparticulate pharmaceutical carriers, and anticancer drugs. In this paper, we present the history of CPPs' discovery with special attention drawn to sequences of viral origin.
