  • Biosynthesis and Rational Design of Novel Pactamycin Analogs

    Creator:
    Abugrain, Mostafa E.
    Abstract:
    Pactamycin, a potent antitumor antibiotic produced by the soil bacterium Streptomycespactum, is a structurally unique aminocyclopentitol-containing natural product. Itconsists of a highly functionalized cyclopentitol core unit, two aromatic rings [3-aminoacetophenone (3AAP) and 6-methylsalicylic acid (6MSA)], and a 1,1-dimethylurea moiety. Despite its potent biological activity, the development of thisantibiotic was hampered...

    Sheng, Yan
    Abstract:
    The discovery of new antibiotics reached its peak during the golden era of antibiotics in the mid 20th century and continued to thrive until the 1980s. However, after more than 50 years of fruitful exploration and exploitation of microbial natural products the discovery rate of new antibiotics has dropped drastically...

  • Biosynthetic engineering of new pactamycins

    Creator:
    Lu, Wanli
    Abstract:
    Among the myriad of naturally occurring bioactive compounds are the aminocyclopentitol-containing natural products that represent a family of sugar-derived microbial secondary metabolites, such as the antibiotics pactamycin, allosamidin, and trehazolin. Pactamycin, a structurally unique aminocyclitol antibiotic isolated from Streptomyces pactum, consists of a 5-membered ring aminocyclitol (cyclopentitol) unit, two aromatic...
