이미지 센서 컬러 필터에 사용하기 위해 새로운 노란색 퀴놀린-다이온 염료 파생물을 설계하고 합성했습니다. 합성된 화합물은 퀴놀린과 디온 그룹으로 구성된 기본 화학 구조를 가지고 있습니다. 새로운 재료는 상업적 장치 제조 공정을 모방한 조건에서 광학적, 열적 특성을 기반으로 평가되었습니다. 이들의 관련 성능을 비교한 결과, 제조된 두 화합물 사이에서 2-(3-hydroxyquinolin-2(1H)-ylidene)-1H-indene-1,3(2H)-dione (HQIDO)이 다음과 같은 우수한 성능을 나타냈습니다. 프로필렌 글리콜 모노메틸 에테르 아세테이트 용매에서 0.5 wt%보다 큰 용해도, 각각 298 ℃의 높은 분해온도를 포함하는 이미지 센서 컬러 필터 재료. 결과는 HQIDO가 이미지 센서 착색제에서 노란색 염료 첨가제로 사용될 수 있음을 시사합니다.

A concise and efficient one-pot synthesis of chroman-2,4-dione-based HKA derivatives by three component reaction of HKAs, triethoxymethane and 4-hydroxycoumarin derivatives under solvent-free and catalyst-free conditions is described. This protocol has many advantages, in that the GAP (Group-Assistant-Purification) chemistry process is involved in this method. As a result, the experimenter can avoid cumbersome process steps such as traditional chromatography and recrystallization purifications. The desired products can be easily obtained by washing the crude products with 95% EtOH.

Two known farnesylacetone derivatives (1 and 2) were isolated from the Korean brown alga Sargassum sagamianum off Jeju Island, Korea. Compounds 1 and 2 were identified as (5E,10Z)-6, 10, 14-trimethylpentadeca-5, 10-dien-2, 12-dione and (5E,9E,13E)-6, 10,4-trimethylpentadeca-5,9,13-trien-2,12-dione, respectively, by comparison with the literature data. Compounds 1 and 2 showed moderate acetylcholinesterase and butyrylcholinesterase inhibitory activities with $IC_{50}$ values of 65.0∼48.0 and 34.0∼23.0 $\muM$, respectively.

1,5-Dihydroxy-3-methoxy-7-methylanthracene-9,10-dione (shiraiarin) is a kind of antitumor and antibacterial anthraquinone, and was produced for the first time from the submerged fermentation of Shiraia bambusicola, as confirmed by ESI-MS and NMR. The production of shiraiarin was significantly influenced when varying the carbon source, and a high amount of shiraiarin was only achieved when using lactose. The production of shiraiarin was also stimulated when using $NaNO_3$ as the nitrogen source, whereas other nitrogen sources inhibited its production. Shiraiarin was formed during the stationary phase with a pH value higher than 8. The production of shiraiarin was inhibited by sporulation.

Trimethylsilylethylsulfide, trimethylsilylphenylsulfide, triethylstannylethylsulfide 그리고 triethylstannylphenysulfide를 10일간 여러온도에서 isocyanate와 각각 반응시켰다. 이들 Si-S와 Sn-S결합 유기금속화합물들은 phenylisocyanate의 이량체, 삼량체, diphenylcarbodiimide 및 1,3,5-triphenyl-4-phenyliminohexahydro-1,3,5-triazine-2,6-dione의 생성 촉매로 작용하였다. 반면 이 화합물들은 ethylisocyanate로부터는 삼량체인 triethylisocyanurate만을 생성하였다.

We prepared 3-aryl-3-hydroxypyrrolidin-2-one and tricyclic 2-benzyl-9b-hydroxy-3,3a,5,9b-tetrahydro-2H-pyrrolo[3,4-c]quinoline-1,4-dione derivatives starting from the Baylis-Hillman adducts of isatin derivatives.

Twenty novel tetramic acid derivatives (E)-3-(1-(alkyloxyamino)ethylidene)-1-alkylpyrrolidine-2,4-diones were synthesized by the reaction of 3-(1-hydroxyethylidene)pyrrolidine-2,4-diones with O-alkyl hydroxylamines. The title compounds were confirmed by IR, $^1H$ NMR, MS and elemental analysis. The structure of compound 6r was further verified by X-ray diffraction crystallography. The bioassays showed that most of the title compounds exhibited noticeable herbicidal and fungicidal activities.

Comparison studies of the Quantitative Structure Activity Relationship (QSAR) methods with new imidazo-quinolinedione derivatives were conducted using Comparative Molecular Field Analysis (CoMFA), Comparative Molecular Similarity Indices Analysis (CoMSIA), and the Hologram Quantitative Structure Activity Relationship (HQSAR). When the CoMFA crossvalidation value, q2, was 0.625, the Pearson correlation coefficient, r2, was 0.973. In CoMSIA, q2 was 0.52 and r2 was 0.979. In the HQSAR, q2 was 0.501 and r2 was 0.924. The best result was obtained using the CoMSIA method according to a comparison of the calculated values with the real in vitro cytotoxic activities against human ovarian cancer cell lines.
