Iso-seco-tanapartholides: Isolation, Synthesis and Biological Evaluation

Synthesis of Novel 17-Oxo-17a-Aza-D-Homo-3, 5-Seco-Steroids as Potential 5α-Reductase Inhibitors

Benign prostatic hyperplasia (BPH) is a non-malignant enlargement of the prostate gland. Itis a leading disorder of the elderly male population. Excessive production of dihydrotestosteronehas been implicated in this pathological condition. Steroidal 5α-reductase is a membrane boundNADPH dependent enzyme which is responsible for the conversion of testosterone (T) todihydrotestosterone (DHT). The...

The stereocontrolled total synthesis of altohyrtin A/spongistatin 1: fragment couplings, completion of the synthesis, analogue generation and biological evaluation.

The antimitotic marine macrolide altohyrtin A/spongistatin 1 has been synthesised in a highly convergent and stereocontrolled manner, thus contributing to the replenishment of the largely exhausted material from the initial isolation work. Coupling of the AB- and CD-spiroacetal subunits by a stereoselective aldol reaction was achieved by using either a lithium (67 : 33 dr) or boron enolate (90 ...

The Synthesis and Pharmacological Evaluation of 2,3 “seco” Fentanyl

Synthesis of some Novel Chromenopyrimidine Derivatives and Evaluation of Their Biological Activities

AbstractPyrimidine nucleosides are constituents of fundamental structure of the cells. There has been considerable attentions in the chemistry of pyrimidine derivatives due to having a wide range of biological activities such as antiviral, anti-malarial agents, cytostatic, antithelemintic, antibacterial, adenosine receptor ligands, anti-cancer agents, compounds targeting delayed-type hypersensi...
