Oxopropalines are novel cytocidal beta-carbolines isolated from Streptomyces . [1]
β-Carboline (9H-pyrido[3,4-b]indole) represents the basic chemical structure for more than one hundred alkaloids and synthetic compounds. The effects of these substances depend on their respective substituent. Natural β-carbolines primarily influence brain functions but can also exhibit antioxidant effects. Synthetically designed β-carboline derivatives have recently been shown to have neuroprotective, cognitive enhancing and anti-cancer properties.
Cephamycins are a group of β-lactam antibiotics. They are very similar to cephalosporins, and the cephamycins are sometimes classified as cephalosporins.
Streptomyces is the largest genus of Actinomycetota, and the type genus of the family Streptomycetaceae. Over 700 species of Streptomyces bacteria have been described. As with the other Actinomycetota, streptomycetes are gram-positive, and have very large genomes with high GC content. Found predominantly in soil and decaying vegetation, most streptomycetes produce spores, and are noted for their distinct "earthy" odor that results from production of a volatile metabolite, geosmin. Different strains of the same species may colonize very diverse environments.
Daptomycin, sold under the brand name Cubicin among others, is a lipopeptide antibiotic used in the treatment of systemic and life-threatening infections caused by Gram-positive organisms.
Dactinomycin, also known as actinomycin D, is a chemotherapy medication used to treat a number of types of cancer. This includes Wilms tumor, rhabdomyosarcoma, Ewing's sarcoma, trophoblastic neoplasm, testicular cancer, and certain types of ovarian cancer. It is given by injection into a vein.
Aclarubicin (INN) or aclacinomycin A is an anthracycline drug that is used in the treatment of cancer in China. It was previously approved for use in Europe but was discontinued in 2004 due to being rarely prescribed and unprofitable.
Streptomyces alboniger is a bacterium species in the genus Streptomyces.
Streptomyces isolates have yielded the majority of human, animal, and agricultural antibiotics, as well as a number of fundamental chemotherapy medicines. Streptomyces is the largest antibiotic-producing genus of Actinomycetota, producing chemotherapy, antibacterial, antifungal, antiparasitic drugs, and immunosuppressants. Streptomyces isolates are typically initiated with the aerial hyphal formation from the mycelium.
Streptomyces antibioticus is a gram-positive bacterium discovered in 1941 by Nobel-prize-winner Selman Waksman and H. Boyd Woodruff. Its name is derived from the Greek "strepto-" meaning "twisted", alluding to this genus' chain-like spore production, and "antibioticus", referring to this species' extensive antibiotic production. Upon its first characterization, it was noted that S. antibioticus produces a distinct soil odor.
Streptomyces albogriseolus is a bacterium species from the genus of Streptomyces which has been isolated from soil. Streptomyces albogriseolus produces neomycin B and neomycin C.
Streptomyces amakusaensis is a bacterium species from the genus of Streptomyces which has been isolated from soil from the Amakusa Island in Japan. Streptomyces amakusaensis produces tuberin and nagstatin.
Streptomyces aurantiogriseus is a bacterium species from the genus Streptomyces which has been isolated from soil in Russia. Streptomyces aurantiogriseus produces differolide and acetamidobenzoic acid.
Streptomyces chrestomyceticus is a bacterium species from the genus of Streptomyces. Streptomyces chrestomyceticus produces lycopene, pyrrolostatin, paromomycin, aminocidin, aminosidin, neomycin E and neomycin F.
Streptomyces griseoaurantiacus is a thermotolerant bacterium species from the genus of Streptomyces which was isolated from marine sediment. Streptomyces griseoaurantiacus produces the antibiotics manumycin, diperamycin and chinikomycin, and griseolic acid.
Streptomyces griseoloalbus is a bacterium species from the genus of Streptomyces which has been isolated from soil. Streptomyces griseoloalbus produces grisein.
Streptomyces griseorubens is a bacterium species from the genus of Streptomyces which has been isolated from soil. Streptomyces griseorubens produces althiomycin. Streptomyces griseorubens produces matamycin and althiomycin.
Streptomyces halstedii is a bacterium species from the genus of Streptomyces which has been isolated from deeper soil layers. Streptomyces halstedii produces magnamycin B, vicenistatin deltamycin A2, deltamycin A3, bafilomycin B1 and bafilomycin C1. Streptomyces halstedii also produces complex antifungal antibiotics like oligomycins and the antibiotics anisomycin and sinefungin.
Streptomyces microflavus is a bacterium species from the genus of Streptomyces which has been isolated from soil. Streptomyces microflavus produces nemadectin, fattiviracin A1, milbemycin and deoxyuridines. Streptomyces microflavus also produces the ionophore valinomycin. Streptomyces microflavus is also known to cause potato common scab disease in Korea.
A jadomycin is a natural product produced by Streptomyces venezuelae ISP5230 (ATCC10712), the organism which is most well known for making the antibiotic chloramphenicol. The name jadomycin is applied to a family of related angucyclines which are distinguished by the E ring, which is derived from an amino acid. The amino acid incorporation which forms the E-ring is a chemical reaction, rather than enzymatic, an uncommon occurrence in biosynthesis. As such a number of jadomycins incorporating different amino acids have been discovered. Jadomycin A was the first compound of this family to be isolated and constitutes the angucylic backbone with L-isoleucine incorporated into the E-ring. A related analog, jadomycin B, is modified by glycosylation with a 2,6-dideoxy sugar, L-digitoxose. Jadomycins have cytotoxic and antibacterial properties.
Estradiol dipropionate/hydroxyprogesterone caproate (EDP/OHPC), sold under the brand name EP Hormone Depot, is a combined estrogen–progestogen medication which is used in Japan. It is manufactured by Teikoku Zoki Pharmaceutical Co., Tokyo and contains 1 mg/mL estradiol dipropionate and 50 mg/mL hydroxyprogesterone caproate.
