여러가지 긴 사슬 지방산 하이드라지드는 방향족과 헤테로 고리 알데히드와 반응하여 알코올 용매하에서 2- hydroxy benzylidene와 새로운 모기 파라-페로몬인1H-indol-3-ylmethylene hydrazides을 얻었다. 마이크로파의 조사기 술과 마찬가지로 전통적인 방법에 의한 다양한 새로운 긴고리 지방산 하이드라지드 (2-hydroxy benzylidene와 1Hindol- 3-ylmethylene)의 합성방법도 보고한다. 이 화합물들의 구조는 FTIR, NMR & MS와 같은 분광학적 기법에 의해 증명되었다. 이 화합물의 전자충격질량스펙트럼 분쇄 패턴의 몇 가지 재미있는 특징도 논의했다. Various long chain aliphatic acid hydrazides react with aromatic and heterocyclic aldehydes in alcoholic medium in refluxing conditions to give corresponding 2-hydroxy benzylidene and 1H-indol-3-ylmethylene hydrazides, a newer class of mosquito para-pheromones. We describe here synthesis of various novel long chain aliphatic acid (2- hydroxy benzylidene and 1H-indol-3-ylmethylene) hydrazides by conventional as well as microwave irradiation techniques. The structures of these compounds have been confirmed by spectroscopic techniques (FTIR, NMR & MS). Some of the interesting features of the electron impact mass spectral fragmentation pattern of these compounds have also been discussed.

We developed and assessed the performance of a new multiplex real-time PCR assay for the detection of all Chlamydia species and simultaneous differentiation of Chlamydia psittaci and Chlamydia pneumoniae—two important human respiratory pathogens—in human clinical specimens. Next-generation sequencing was used to identify unique targets to design real-time PCR assays targeting all Chlamydia species, C. psittaci, and C. pneumoniae. To validate the assay, we used a panel of 49 culture isolates comprising seven C. psittaci genotypes, eight C. pneumoniae isolates, seven other Chlamydia species, and 22 near-neighbor bacterial and viral isolates, along with 22 specimens from external quality assessment (EQA) panels and 34 nasopharyngeal and oropharyngeal swabs and cerebrospinal fluid, stool, and sputum specimens previously identified as positive or negative for C. psittaci or C. pneumoniae. The assays were 100% specific, with limits of detection of 7.64– 9.02 fg/μL. The assay results matched with historical assay results for all specimens, except for one owing to the increased sensitivity of the new C. psittaci assay; the results of the EQA specimens were 100% accurate. This assay may improve the timely and accurate clinical diagnosis of Chlamydia infections and provide a greater understanding of the burden of disease caused by these agents.
