Abstract

Highlights
•
The role of the C7-OH group in the activity of cylindrospermopsin 1 is unknown.
•
Synthetic analogues (11a–c) of cylindrospermopsin 1 were prepared.
•
Toxicity of these analogues was compared with 1 using human neutrophils in vitro.
•
The greatest toxicity was found in 11c with a 6-carbon tether and an –OH group.
•
An analogue closely resembling 1 but lacking the C7-OH group had low toxicity.
