    • An eighteen amino acid neuropeptide isolated from brain complexes of adult female cockroach, Diploptera punctata, is identified as an allatostatin because it inhibits the biosynthesis of juvenile growth hormone in cockroach corpora allata. Primary structure of the isolated allatostatin is Al a-Tyr-Ser-Tyr-Val-Ser-Glu-Tyr-Lys-Arg-Leu-Pro-Val-Tyr-Asn-Phe-Gly-Leu-NH.sub.2. A synthetic peptide of this sequence and three synthetic peptides with truncated sequences conserving the amidated carboxyl portion of the native sequence have allatostatin activity. Certain derivatives of the peptides also have allatostatin activity including compounds having the sequence: X-Val-Tyr-Asn-Phe-Gly-Leu-NH.sub.2, in which X is Leu-Arg, Leu-Pro, Arg-Leu-Pro-, Ala-Tyr-Ser-Tyr-Val-Ser-Glu-Tyr-Lys-Arg-Leu-Pro, acetyl-Ala-Tyr-Ser-Tyr-Val-Ser-Glu-Tyr-Lys-Arg-Leu-Pro, or acetyl-Arg-Leu-Pro. These peptides have the potential for regulating the growth of certain insects, and may be useful in the area of insect control.
    • 从成年雌性蟑螂(Diploptera punctata)的脑复合物中分离出的十八个氨基酸神经肽被鉴定为全收养素抑制因子,因为它抑制蟑螂中的幼体生长激素的生物合成。 分离的全收养素的一级结构是Al a-Tyr-Ser-Tyr-Val-Ser-Glu-Tyr-Lys-Arg-Leu-Pro-Val-Tyr-Asn-Phe-Gly-Leu-NH 2。 该序列的合成肽和保留天然序列的酰胺化羧基部分的具有截短序列的三个合成肽具有保护素的活性。 肽的某些衍生物还具有全胃肠抑素活性,包括具有以下序列的化合物:X-Val-Tyr-Asn-Phe-Gly-Leu-NH 2,其中X为Leu-Arg,Leu-Pro,Arg-Leu-Pro- Ala-Tyr-Ser-Tyr-Val-Ser-Glu-Tyr-Lys-Arg-Leu-Pro,乙酰基-Ila-Tyr-Ser-Tyr-Val-Ser-Glu-Tyr-Lys-Arg-Leu-Pro, 或乙酰基-Arg-Leu-Pro。 这些肽具有调节某些昆虫生长的潜力,并且可能在昆虫控制领域是有用的。
