How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Muhammad Nouman Ahmed currently works as PhD researcher at the Department of Microbiology, University of Helsinki. Muhammad does research in Microbiology, Bioinformatics, Biotechnology and Medicinal Chemistry. Now my PhD project revolves around the identification and characterization of selective inhibitors of human trypsin isoforms from cyanobacteria to prevent the metastasis.
Low-molecular weight natural products display vast structural diversity and have played a key role in the development of novel therapeutics. Here we report the discovery of novel members of the aeruginosin family of natural products, which we named varlaxins. The chemical structures of varlaxins 1046A and 1022A were determined using a combination o...
Serine proteases regulate many physiological processes and play a key role in a variety of cancers. Aeruginosins are a family of natural products produced by cyanobacteria that exhibit pronounced structural diversity and potent serine protease inhibition. Here, we sequenced the complete genome of Nodularia sphaerocarpa UHCC 0038 and identified the...
Trypsin-3 is a highly active protease that has recently been identified as a potential therapeutic target for the reduction of tumor growth and metastasis in prostate, breast and pancreatic cancers. Current trypsin inhibitors typically inhibit a broad range of different trypsin-like enzymes. Thus, novel approaches to identify trypsin-3 selective in...
Natural products and their semi-synthetic derivatives are an important source of drugs for the pharmaceutical industry. Bacteria are prolific producers of natural products and encode a vast diversity of natural product biosynthetic gene clusters. However, much of this diversity is inaccessible to natural product discovery. Here we use a combination...
