Paragraph 0096-0097; 0108-0110; 0123-0124; 0132-0134, (2021/08/07)
The invention relates to a microenvironment response type amphiphilic dendrimer, a synthesis method thereof, and application of the microenvironment response type amphiphilic dendrimer as a drug delivery system. The microenvironment response type amphiphilic dendrimer is a compound with a structure as shown in a formula (I), a formula (II) or a formula (III) or pharmaceutically acceptable salt of the compound. The compound disclosed by the invention can be used as the nano delivery system based on tumor microenvironment specific response, has good solubility in an aqueous solution, can be self-assembled with a drug in the aqueous solution to form a relatively stable nano compound, can effectively deliver the loaded drug to a tumor site; and can responsively disassembl the nano-drug delivery carrier under corresponding stimulation to achieve the purpose of accurate drug release, so that the drug can be released to the focus part to the greatest extent, and the compound is a novel nano-delivery carrier.

3-(2-aminophenyl)-4-methyl-1,3-thiazole-2(3H)-thione as an ecofriendly sulphur transfer agent to prepare alkanethiols in high yield and high purity
Mehdid, Mohammed Amine,Djafri, Ayada,Roussel, Christian,Andreoli, Federico
experimental part, p. 4634 - 4643 (2010/04/06)
A new process is described for preparing very pure linear alkanethiols and linear α,ω-alkanedithiols using a sequential alkylation of the title compound, followed by a ring closure to quantitatively give the corresponding 3-methyl[1,3]thiazolo[3,2-a]-[3,1
L-Cysteine as a water-soluble cation scavenger in the removal of the 2,4,6-trimethoxybenzyl group from thiols
Lin, Chia-En,Richardson, Stewart K,Garvey, David S
, p. 4531 - 4533 (2007/10/03)
L-Cysteine was used as a water-soluble cation scavenger in the acid-catalyzed removal of the 2,4,6-trimethoxybenzyl (Tmob) group from thiols. After aqueous extraction, the product thiols were isolated in good yields. For most substrates, trifluoroacetic acid (TFA) is the reagent of choice. However, for the deprotection of acid-sensitive compounds, formic acid with an extended reaction time is appropriate.
