Autor: QiQi Cheng, Leher Singh, Yen Ling Low, Seok Hui Tan, Agnes L. Tan

Publikováno v: Child developmentREFERENCES. 93(1)

In this study, infant vocabulary development was tracked in a multilingual society (Singapore) within a socioeconomically diverse sample. The sample comprised 1316 infants from 17.4 to 27.7 months (669 females, 647 males; 88% Chinese race, 4% Malay,

Structure—activity relationships of some indolo[3,2-c]quinolines with antimalarial activity

Autor: Agnes L. Tan, Prapon Wilairat, Kunnika Kuaha, Mei-Lin Go, Tong Lan Ngiam

Publikováno v: European Journal of Pharmaceutical Sciences. 6:19-26

The synthesis, physicochemical characterization and in vitro antimalarial activity of a series of indolo[3,2-c]quinolines (9a-f) are described. There is only a poor correlation between the activity and hydrophobicity. In contrast, 33% of the observed

Addition of BiCl3 to [Pt2(PPh3)4(μ-S)2] gives [Pt2(PPh3)4(μ3-S)2BiCl3], which undergoes dissociation and metathesis with NH4PF6 to give [Pt2(PPh3)4(μ3-S)2BiCl2]PF6. An X-ray single-crystal diffraction analysis established two highly distorted squa
