본 발명은 미세조류 파괴용 조성물에 관한 것으로, 더욱 자세하게는 특정 치환기를 가지는 나프토퀴논 화합물을 함유하는 미세조류 파괴용 조성물에 관한 것이다. 본 발명에 따른 신규한 미세조류 파괴용 조성물은 해양 미세조류 배양장 또는 녹조 또는 적조가 발생된 지역 또는 녹조나 적조 발생 예상 지역에 처리하여 녹조 및 적조 피해를 예방할 수 있는 효과가 있다.
We followed a simple, inexpensive, and efficient route to synthesize a series of 3,4-dihydrobenzo[f]quinoxalin-6(2H)-one derivatives substituted in the ring B, with the expectation that this scaffold might exhibit antineoplastic activity. 5-Chlorobenzo[f]quinoxalin-6-ylacetate and 4-benzylbenzo[f]quinoxalin-6(4H)-one were obtained for the first time.
我们遵循一种简单,廉价且有效的途径,合成了在环B中取代的一系列3,4-二氢苯并[ f ]喹喔啉-6(2 H)-one衍生物,并期望该支架可能具有抗肿瘤活性。首次获得5-氯苯并[ f ]喹喔啉-6-乙酸盐和4-苄基苯并[ f ]喹喔啉-6(4 H)-one。

Here we report the nanomolar potencies of N 1,N 3-dialkyldioxonaphthoimidazoliums against asexual forms of sensitive and resistant Plasmodium falciparum. Activity was dependent on the presence of the fused quinone-imidazolium entity and lipophilicity imparted by the N1/N3 alkyl residues on the scaffold. Gametocytocidal activity was also detected, with most members active at IC50 < 1 μM. A representative

N-substituents induces conformational changes that apparently modify the nature and number of donor–acceptor sites for noncovalent interactions, leading to diverse crystal packing patterns. Interestingly, the introduction of 2-(benzylamino)- and 2-(2-pyridylmethylamino)- substituents in 2 and 4 successfully switched on the C–Cl⋯π synthon, which is scarcely seen in the crystal packing of organic molecules
coupling of 2-amino-3-chloro-1,4-naphthoquinones with amines is described. The scope and limitations of the coupling process using [1,1 '-bis(diphenylphosphino)ferrocene] dichloropalladium [PdCl 2 (dppf)], combined with 1,1'-bis(diphenylphosphino)ferrocene (dppf) as a ligand and sodium tert-butoxide as base were investigated, and found to catalyze efficiently the coupling of 2-(arylamino)-3-chloro- 1,4-naphthoquinones
