Nowadays, our aquatic environment is currently being polluted by harmful algal blooms, which affect water quality and eventually kill aquatic organisms. Many efforts have been carried out to overcome the problem but the methods are either money-consuming or non-environmental friendly. Therefore, this study was aimed to inhibit the growth of Oscillatoria sp. isolated from Kenyir lake in the state of Terengganu, Malaysia using the synthesized pentyl-thiourea derivatives (1-4). The series of compounds were successfully synthesized and spectroscopically characterized via infrared analysis and 1H and 13C NMR spectroscopy. The IR spectra of all the compounds showed five expected important stretching bands of interest which were n(N-H), n(C-H), n(C=O), n(C-N) and n(C=S). In turn, they were introduced towards Oscillatoria sp. culture at different concentration of 2-10 μg/mL. All these compounds showed inhibition potential towards the Oscillatoria sp. growth in the range of 6 and 30 %. These types of molecules within thiourea family are indeed are potentially exhibit the growth of Oscillatoria sp.

生物。为了解决这个问题,人们做了很多努力,但这些方法要么耗资巨大,要么不环保。因此,本研究旨在利用合成的戊基
硫脲衍
生物(1-4)抑制从马来西亚丁加奴州 Kenyir 湖中分离出来的 Oscillatoria sp.成功合成了这一系列化合物,并通过红外分析、1H 和 13C NMR 光谱对其进行了表征。所有化合物的红外光谱都显示出五个预期的重要伸展带,即 n(N-H)、n(C-H)、 n(C=O)、 n(C-N)和 n(C=S)。然后,以 2-10 μg/mL 的不同浓度将这些化合物引入
鞘氨醇培养基。所有这些化合物都对震旦蓟马的生长有抑制作用,抑制率在 6% 和 30% 之间。这些类型的
硫脲家族分子确实有可能抑制震旦蓟马的生长。
