A number of inhibitors of methyl farnesoate epoxidase of Blaberus glganteus corpora allata have been described (18). They include typical cytochrome P-450 monooxygenase inhibitors such as methylenedloxyphenyl compounds and substituted imidazoles. In assays of JH III biosynthesis by Perlplaneta amerlcana CA in vitro some methylenedloxyphenyl compounds were shown to inhibit hormone production at moderate to high concentrations (19). Both methylenedloxyphenyl compounds and terpenoid imidazoles have also some anti-juvenile hormone activity in Lepidoptera (7, 20). 

Since that time many more sequences have become available through the advent of recombinant DNA technology and the deduction of amino acid sequences from the base sequences of cloned DNA. At the present time, the primary structures (amino acid sequences) of 14 proteins of the transferrin family have been established. These include seven serum transferrins, from human 10, 36), pig (37), horse 38), rabbit 39), toad Xenopus laevis) 40), sphinx moth (M. sexta) 13), and cockroach Blaberus discoidalis 4) chicken 34, 35) and duck 41) ovotransfer-rins four lactoferrins, from human (11, 42), mouse 43), pig 44) and cattle 45, 46) and the human tumor cell melanotransferrin 47). All of these sequences are available from sequence databases such as EMBL and SWISSPROT.

Figure 3. Effects of bioanalogs of Blaberus hypertrehalosemic hormone on cytoheme ab synthesis in the fat body of 4-day old, adult male B, discoidalis. Values are mean+SEM. All animals were decapitated on day 0 and received 20 pmoles of peptide on days 2,3 and 4 followed by measurement of cytoheme cb synthesis on day 4.
