This paper reviews the synthesis, characterization, biodegradation and usage of bioresorbable polymers based on polydepsipeptides. The ring-opening polymerization of morpholine-2,5-dione derivatives using organic Sn and enzyme lipase is discussed. The dependence of the macroscopic properties of the block copolymers on their structure is also presented. Bioresorbable polymers based on polydepsip...

The Antibiogram properties of 1-chloro-2-isocyanatoethane derivatives of thiomorpholine (CTC), piperazine (CPC) and morpholine (CMC) were evaluated by the approved agar well diffusion, the minimum inhibitory concentration (MIC) and in silico techniques. A total of fourteen microbial cultures consisting of ten bacteria and four yeast strains were used in the biological study while affinity of th...

The synthesis of 3-morpholino-7-[N-methyl-N-(4′-carboxyphenyl)amino]phenothiazinium chloride is reported here. Interestingly, non-symmetric phenothiazinium salt functionalized with a carboxylic acid group that allows the easy and stable anchoring on metal oxides. In addition, morpholine unit reduces dye aggregation tendency; thus, improving its potential applications in biomedical photo-electro...
