The co-crystalstructure of Compound 6b with tubulin was prepared and solved for indicating the binding mode and for further optimization. Based on the co-crystalstructures of tubulin with plinabulin and Compound 6b, a total of 27 novel A/B/C-rings plinabulinderivatives were designed and synthesized. Their biological activities were evaluated against human lung cancer NCI-H460 cell line. The optimum

3-Phenoxybenzyl alcohols and carboxylic acid esters thereof for combating pests of the formula ##STR1## in which R and R.sup.1 are different and each represent hydrogen, fluorine or bromine, R.sup.2 represents cyano or ethynyl and R.sup.3 represents the ##STR2## or the ##STR3## wherein the phenyl ring can optionally carry one or more substituents selected independently from halogen, alkyl, alkylthio and alkoxy with in each case 1 to 4 carbon atoms, nitro and methylenedioxy, and R.sup.4 and R.sup.5 are identical and each represent chlorine, bromine or methyl, and R.sup.2 represents hydrogen in case that R.sup.3 represents the ##STR4## wherein R.sup.4 and R.sup.5 are identical and each represent chlorine or bromine and R.sup.3 represents the ##STR5## wherein the phenyl ring can carry the above mentioned substituents which possess insecticidal and acaricidal properties. The benzyl alcohols from which the esters are made are also new.
