Platform Chemicals, also known as building block chemicals, are a fast growing segment of the Global Green Chemicals market. They are composed of 2-6 carbons that are used as an intermediate in the production of various organic chemicals. Because of the scarcity of fossilbased feedstock and rising awareness about sustainable environment, renewable resources are used in the production of bio-based platform chemicals. In addition, rapidly developing technology has made it possible to use microbial strains in the manufacture of chemicals.

Styrene is also known as vinylbenzene, phenylethane, and ethenylbenzene. It is a colorless, flammable, water insoluble, and oily organic compound. The chemical is a derivative of benzene and is prepared from dehydrogenation of ethylbenzene. Styrene evaporates easily, emits a sweet odor, and has a high tendency to undergo polymerization and copolymerization. It is a co-product obtained during the production of propylene oxide through the POSM process.

Styrenic block copolymers, commonly known as SBC, belong to the family of thermoplastic elastomers. SBCs are consumed in bulk compared to other thermoplastic elastomers and have properties similar to rubber, though they are processed as thermoplastics. SBC is added in additives and other high-performance polymeric compounds for the formulation of the final end-products. The major end-use markets of SBC include the Footwear industry, the Paving and Roofing industry, the Medical and Personal Care industries, and several others. SBCs possess unique properties such as recyclability, elastic quality, and good flexibility at lower temperatures.

Toluene, also known as methylbenzene, is an aromatic hydrocarbon that contains seven carbon and eight hydrogen atoms. It is represented by the formula C7H8. Toluene is produced during the manufacture of gasoline by naptha reforming. Reformate accounts for more than seventy percent of the global toluene production and the rest comes from pygas. It is a clear and colorless liquid with low volatility owing to the methyl group in its chemical structure, which also makes it a good octane enhancer for gasoline blending. It is used as a raw material for the production of benzene, solvents, xylene, and TDI, which are further used in several end-user industries such as Paint, Adhesive, Chemical, Pharmaceutical, Textile, Polymer, and Plastic.

合成了七元环的杂化合物2a~2k,并发现化合物2a~2k会向其同分异构体六元环内酰胺3a~3k转化。化合物2a~2k的结构通过红外光谱(IR)、核磁共振波谱(NMR)、质谱(MS)和元素分析确证。初步的抑菌活性测试结果表明，化合物2a~2k对白色念珠菌、标准新生隐球菌、临床新生隐球菌、大肠杆菌和枯草牙孢杆菌均有较好的抑菌活性，而六元环内酰胺3a~3k对所测菌种没有活性。实验还测定了部分混合物(2a~2e和3a~3e)的抑菌活性，结果表明化合物2a~2e和3a~3e混合物的抑真菌效果比单一的化合物2a~2e要好，化合物3a~3e的存在增强了化合物2a~2e的抑菌活性。

以3-芳基/烷基-4-氨基-5-巯基-1,2,4-三唑为原料，经过环化和糖化反应，设计合成了10个未见报道的化合物3-芳基/烷基-6-S-2’,3’,4’,6’-四-O-乙酰基-β-D-吡喃葡萄糖基-1,2,4-三唑并[3,4-b]-1,3,4-噻二唑(3a~3j)，其结构经核磁共振波谱、高分辨质谱和红外光谱确认。生物活性测试表明,所有化合物均对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌和白色念株菌表现出一定的抗菌活性，其中化合物3c对4种测试菌株的最小抑菌浓度(MIC)最低，且接近于氟康唑的参照数据，具有较强的抗菌活性。利用Auto Dock 4.0程序研究了目标化合物3a~3j与大肠杆菌FabⅠ受体蛋白分子的相互作用和结合自由能变化规律。
