Pingyangmycin (also known as bleomycin A5) is an antitumor glycopeptide antibiotic belonging to the bleomycin family, which is produced by Streptomyces verticillus var. pingyangensis n.sp., a variety of Streptomyces verticillus . It was discovered in 1969 at Pingyang County of Zhejiang Province in China, and was brought into clinical use in 1978. [1]
In China, pingyangmycin has largely superseded bleomycin A2 (commonly known as "bleomycin"), since according to Chinese sources it is more effective, costs less, is easier to get, can treat a larger variety of cancers (such as breast cancer and liver cancer) and causes less lung injury. [2] [3] Though pingyangmycin and bleomycin can each cause pulmonary fibrosis, pingyangmycin's most serious side effect - which it does not share with bleomycin - is anaphylactic shock, which is rare, but may happen even in a low dose, and can be fatal. [4] In addition, it causes a higher incidence of fever than bleomycin; the occurrence of this complication in patients is between 20 and 50%.
Bleomycin is a medication used to treat cancer. This includes Hodgkin's lymphoma, non-Hodgkin's lymphoma, testicular cancer, ovarian cancer, and cervical cancer among others. Typically used with other cancer medications, it can be given intravenously, by injection into a muscle or under the skin. It may also be administered inside the chest to help prevent the recurrence of a fluid around the lung due to cancer; however talc is better for this.
Palate, lung, and nasal epithelium clone protein (PLUNC) is a gene encoding a secretory protein. It is also called Secretory protein in upper respiratory tracts (SPURT). In humans, it is encoded by the BPIFA1 gene, previously called PLUNC.
Electrochemotherapy is a type of chemotherapy that allows delivery of non-permeant drugs to the cell interior. It is based on the local application of short and intense electric pulses that transiently permeabilize the cell membrane, thus allowing transport of molecules otherwise not permitted by the membrane. Applications for treatment of cutaneous and subcutaneous tumors have reached clinical use by utilizing drugs such as bleomycin or cisplatin). Electrochemotherapy with bleomycin was used to treat a patient for the first time in 1991 at the Institute Gustave Roussy in France, while electrochemotherapy with cisplatin was used to treat for the first time in 1995 at the Institute of Oncology, Ljubljana, Slovenia. Since then, more than 4000 patients were treated with electrochemotherapy all over the world. Recently, new electrochemotherapy modalities have been developed for treatment of internal tumors using surgical procedures, endoscopic routes, or percutaneous approaches to gain access to the treatment area.
Polypeptide antibiotics are a chemically diverse class of anti-infective and antitumor antibiotics containing non-protein polypeptide chains. Examples of this class include actinomycin, bacitracin, colistin, and polymyxin B. Actinomycin-D has found use in cancer chemotherapy. Most other polypeptide antibiotics are too toxic for systemic administration, but can safely be administered topically to the skin as an antiseptic for shallow cuts and abrasions.
Sho-Saiko-To, also known as Minor Bupuleurum Formula and Xiǎocháihútāng (XCHT) in Chinese, is a herbal supplement, believed to enhance liver health. Sho-Saiko-To is a widely used prescription drug in China and is a listed formula in China and Japan as a Kampo medicine. There are currently ongoing clinical trials for Sho-Saiko-To at University of California, San Diego and Memorial Sloan-Kettering Cancer Center. The active ingredients of Sho-Saiko-To discovered so far include: Baicalin, baicalein, glycyrrhizin, Saikosaponins, ginsenosides, wogonin, gingerol.
Semustine is an alkylating nitrosourea compound used in chemotherapy treatment of various types of tumours. Due to its lipophilic property, semustine can cross the blood-brain barrier for the chemotherapy of brain tumours, where it interferes with the cellular DNA of the highly dividing cells. Semustine, just as lomustine, is administered orally. It has been reported that semustine can perform the main mechanism of action at molecular level via the alkylation of DNA nitrogenous bases in duplex by results of inhibition of DNA replication, transcription, and translation by way of alkylation of DNA, under pH-dependent conditions by hydrolysis, forming chloro-carbonium ions. Sufficient evidence was found that treatment with semustine can cause acute leukaemia as a delayed effect in very rare cases.
Huáng bǎi, huáng bó or huáng bò is one of the fifty fundamental herbs of traditional Chinese medicine. Known also as Cortex Phellodendri, it is the bark of one of two species of Phellodendron tree: Phellodendron amurense or Phellodendron chinense.
Bufothionine is a sulfur-containing compound which is present in the bufotoxins secreted by the parotoid gland of certain toads of the genera Bufo and Chaunus. This specific compound can be found in the skin of certain species of toad such as the Asiatic Toad, Chaunus arunco, Chaunus crucifer, Chaunus spinulosus, and Chaunus arenarum.
Elemenes are a group of closely related natural chemical compounds found in a variety of plants. The elemenes, which include α-, β-, γ-, and δ-elemene, are structural isomers of each other and are classified as sesquiterpenes. The elemenes contribute to the floral aromas of some plants, and are used as pheromones by some insects.
In molecular biology mir-425 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
In molecular biology mir-28 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
In molecular biology mir-638 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
GTP-binding protein Di-Ras3 (DIRAS3) also known as aplysia ras homology member I (ARHI) is a protein that in humans is encoded by the DIRAS3 gene.
STEAP family member 4 is a protein that in humans is encoded by the STEAP4 gene.
Streptomyces flavoviridis is a bacterium species from the genus of Streptomyces which has been isolated from soil. Streptomyces flavoviridis produces phleomycin and zorbamycin.
Thrombin–antithrombin complex (TAT) is a protein complex of thrombin and antithrombin. It is a marker of net activation of coagulation.
CKLF-like MARVEL transmembrane domain-containing protein 3, also termed chemokine-like factor superfamily 3, is a member of the CKLF-like MARVEL transmembrane domain-containing family of proteins. In humans, CMTM2 protein is encoded by the CMTM3 gene located in band 22.1 on the long arm of chromosome 16. This protein is expressed in a wide range of tissues, including fetal tissues. It is highly expressed in the male reproductive system, particularly testicular tissues and may play a role in the development of this tissue. It is also highly expressed in the immune system including circulating blood cells, i.e. B lymphocytes, CD4+ T lymphocytes, and monocytes. However, CMTM3 protein is weakly expressed or unexpressed in the malignant tissues of several types of cancers. In many but not all of theses cancers, this decreased or lack of expression appears due to methylation of the GpC islands in the promoter region, and thereby the silencing, of the CMTM3 gene.
C-1027 or Lidamycin is an antitumor antibiotic consisting of a complex of an enediyne chromophore and an apoprotein. It shows antibiotic activity against most Gram-positive bacteria. It is one of the most potent cytotoxic molecules known, due to its induction of a higher ratio of DNA double-strand breaks than single-strand breaks.
Securinine is an alkaloid found in Securinega suffruticosa and Phyllanthus niruri.
CKLF-like MARVEL transmembrane domain-containing 5 (CMTM5), previously termed chemokine-like factor superfamily 5, designates any one of the six protein isoforms encoded by six different alterrnative splices of its gene, CMTM5; CMTM5-v1 is the most studied of these isoforms. The CMTM5 gene is located in band 11.2 on the long arm of chromosome 14.
