Characterisation of novel anti-HIV/tuberculosis natural product analogues.
Non-nucleoside reverse-transcriptase inhibitors (NNRTIs) are one of the key components of antiretroviral drug regimens against human immunodeficiency virus type 1 (HIV-1) replication. (+)-calanolide A, which is purified from the rainforest plant Calophyllum, is an anti-HIV-1/ tuberculosis drug. In our previous study, a library of (+)-calanolide A was constructed and one novel compound 10-chloro...
متن کاملDiosgenone synthesis, anti-malarial activity and QSAR of analogues of this natural product.
Solanum nudum Dunal steroids have been reported as being antimalarial compounds; however, their concentration in plants is low, meaning that the species could be threatened by over-harvesting for this purpose. Swern oxidation was used for hemisynthesis of diosgenone (one of the most active steroidal sapogenin diosgenin compounds). Eighteen structural analogues were prepared; three of them were ...
متن کاملSynthesis and Anti-Tuberculosis Activity of the Marine Natural Product Caulerpin and Its Analogues
Caulerpin (1a), a bis-indole alkaloid from the marine algal Caulerpa sp., was synthesized in three reaction steps with an overall yield of 11%. The caulerpin analogues (1b-1g) were prepared using the same synthetic pathway with overall yields between 3% and 8%. The key reaction involved a radical oxidative aromatic substitution involving xanthate (3) and 3-formylindole compounds (4a-4g). All bi...
متن کاملNatural Product Synthesis
The Lycopodium alkaloids are a family of structurally complex natural products, which have provoked long-term interests in their total syntheses because of their unique and fascinating architectures and potential biological activities. In particular, fawcettimine-type Lycopodium alkaloids, such as fawcettimine (1) and fawcettidine (2) (Scheme 1), have attracted broad attention from the syntheti...
متن کاملHigh-throughput, microarray-based synthesis of natural product analogues via in vitro metabolic pathway construction.
The generation of biological diversity by engineering the biosynthetic gene assembly of metabolic pathway enzymes has led to a wide range of "unnatural" variants of natural products. However, current biosynthetic techniques do not allow the rapid manipulation of pathway components and are often fundamentally limited by the compatibility of new pathways, their gene expression, and the resulting ...
