Nikkomycins are a group of peptidyl nucleoside antibiotics with potent fungicidal, insecticidal, and acaricidal activities. sanN was cloned from the partial genomic library of Streptomyces ansochromogenes 7100. Gene disruption and complementation analysis demonstrated that sanN is essential for nikkomycin biosynthesis in S. ansochromogenes. Primer extension assay indicated that sanN is transcri...

In the title compound, C(24)H(29)N(3)O(2), the dihedral angle between the benzene and pyrazole rings is 80.55 (7)°. The mol-ecule contains an acrylonitrile moiety and exists in an E conformation. Bioassay tests showed that the title compound exhibited higher acaricidal activity than its Z isomer.

We examined the cytotoxic effects of dillapiole, a phenylpropanoid with antileishmanial, anti-inflammatory, antifungal, and acaricidal activities, on the blastocyst stage of mouse embryos, subsequent embryonic attachment and outgrowth in vitro, and in vivo implantation via embryo transfer. Blastocysts treated with 2.5-10 μM dillapiole exhibited a significant increase in apoptosis and correspond...

Milbemycins are a family of sixteen-membered macrolides produced by Streptomyces hygroscopicus subsp. aureolacrimosus. They exhibit broad-spectrum insecticidal and acaricidal activity. * ~ 3) In the course of our studies on the microbial conversion of milbemycins, we obtained 13/?hydroxymilbemycins A4, A3, D, 13/Miydroxy-LLF28249a, 28-hydroxymilbemycin D, and 28-hydroxy-LL-F28249a by using Cunn...

BACKGROUND House dust mite allergen levels in humid coastal regions of Australia are high, particularly in beds. Because high allergen levels in beds are associated with more severe asthma, reduction of levels may be important for asthma control. OBJECTIVE We tested the effectiveness of an acaricidal treatment of bedding in combination with occlusive mattress and pillow encasings in reducing ...

two spotted spider mite (tssm), tetranychus urticae koch, is an important pests on bean in markazi province (center of iran). to evaluate the bioacaricidal activity of extracts of three essential oils of thyme (thymus vulgaris), lavender (lavandula officinalis)  and eucalyptus (eucalyptus camaldulensis) against t. urticae on cherry bean (vigna unguiculta subsp. sinensis), five different concent...
