Five triorganotin（IV）（1-5） complexes of cinnamic acid, （Z）-2-acetamido-3-phenylacrylic acid, 3-methylbut-2-enoic acid, and 2,2-diphenylacetic acid have been synthesized and characterized by IH-13C-119Sn NMR, UV, and IR. The spectroscopic investigation demonstrated that the carboxylate group acts as a monodentate ligand in triorganotin（IV） compounds. Five triorganotin（IV） complexes were screened against the log phase culture of Mycobacterium tuberculosis H37Rv by colorimetric method using XTT dye as growth indicator. The MICs were found to he 0.08 and 1.25μg/mL.

4-(R-Phenylazo)-2-methyl quinoline derivatives form (1:1) complexes with nickel chloride, nickel acetate and copper acetate which were syntheses. The three complexes are non-electrolyte in dimethylsulfoxide (DMF). The results of electronic and magnetic measurements show that these complexes are of octahedral structures. The oxygen and nitrogen donate their lone-pair electrons to metal ion to form chelates with formula [***2O]. The relative stabilities of the complexes have been calculated from TG curve using Coats-Redfern and Ozawa methods.

　　The Amaryllidaceae alkaloids have attracted considerable attention for their interesting biological activities. [1] Many of these tyrosine derived alkaloids[2] incorporate a hexahydroindole moiety in the structural skeletons. New approaches towards the synthesis of hexahydroindole core have been a topical interest for the synthetic *** we report an experimentally very simple method for the synthesis of hexahydroindole by aminocylization. Four kinds of N-substituted have been demonstrate to be effective to this cyclization. The results were summarized in Figure 1.……

Abstract: One amino acid modified phthalocyanine was synthesized and its absorption was measured. And a red shift up to 25 nm relative to ZnPc(NH2)4 was *** recent years, phthalocyanines are widely used in photodynamic therapy (PDT) and ligntinduced eleCtronic d..ices(i), because they can be potentially used in the therapy of cancer andin the restraint of human immunology virus (HIV)etcq'. In order to study the relationship betweenthe molecular struCture and its propeFties, various kinds of phthaloCyanines have beensynthesized, however phthaiocyanines modified by amino acid have not been reported it isexpeCted that the introduCtian of an amino acid group onto the phthalocyanine molecuje cauldimprove the solubility of such dyes in physiological system. In this work,a phthalocyaninemodified by glycine was synthesized and identified by conventional method, and its UV- Visspectra were obtained.

A high speed data sampling system on dynamic Oscillographic analysis was established with a 80386DX40 computer, AD 674 and flow injection system. Programs were designed in Microsoft Windows 3.1, that can process E-t, dE/dt-t, i'(f)-t and other kinds of curve on oscillographic analysis. A satisfactory result on determination of Pb2+ and Cd2+ was obtained.
