Synthesis And Biological Evaluation

In the present study, a series of benzothiazol derivatives 3a-l containing pyrazolo[3,4-d]pyrimidine moiety at the second position were synthesized and characterized by analytical and spectral data. The compounds were tested for their in vitro antimicrobial activity. Compounds 1-(1,3-benzothiazol-2- yl)-3-methyl-4-phenyl-1H-pyrazolo[3,4-d]pyrimidine (3a), 1- (1,3-benzothiazol-2-yl)-4-(4-chlorophenyl)-3-methyl-1H-pyrazolo[ 3,4-d]pyrimidine (3d) and 1-(1,3-benzothiazol-2-yl)- 3-methyl-4-substituted phenyl-1H-pyrazolo[3,4-d]pyrimidines (3h-j) showed significant inhibitory activity against P. aeruginosa whereas compounds 1-(1,3-benzothiazol-2-yl)-4- (2-chlorophenyl)-3-methyl-1H-pyrazolo[3,4-d]pyrimidine (3b), 2-[1-(1,3-benzothiazol-2-yl)-3-methyl-1H-pyrazolo[3,4-d]pyrimidin- 4-yl]phenol (3e), 1-(1,3-benzothiazol-2-yl)-4-(3,4-dimethoxyphenyl)- 3-methyl-1H-pyrazolo[3,4-d]pyrimidine (3h), 4-[1-(1,3-benzothiazol-2-yl)-3-methyl-1H-pyrazolo[3,4-d]pyri midin-4-yl]-N,N-dimethylaniline (3j) and 1-(1,3-benzothiazol- 2-yl)-3-methyl-4-[2-phenylvinyl]-1H-pyrazolo[3,4-d]pyrimidine (3k) were found to be active against C. albicans. Some of these synthesized compounds were evaluated for their in vivo acute toxicity, analgesic, anti-inflammatory, and ulcerogenic actions. The tested compound 4-[1-(1,3-benzothiazol- 2-yl)-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-yl]-N, N-dimethylaniline (3j) exhibited maximum analgesic and anti-inflammatory activities. Compounds 1-(1,3-benzothiazol- -2-yl)-3-methyl-4-(3-nitrophenyl)-1H-pyrazolo[3,4-d]pyrimidine (3i) and 3j showed a significant gastrointestinal protection compared to the standard drug diclofenac sodium.

Series of novel substituted Synthesis of N-{[5-(substituted)-1,3,4-oxadiazole-2-yl] carbamothioyl} derivatives containing 1,3,4-oxadiazole moiety were synthesized by microwave as a green chemistry method and conventional method by using pyridine 3- carboxylic acid as a starting material. The structures of the synthesized compounds were characterized by physicochemical data, IR, Mass spectra and 1HNMR. All the newly synthesized compound screened for their antimicrobial and In-vivo and In-vitro Anti-inflammatory studies. Anti-inflammatory studies revealed that compound 4f showed significant in-vivo and in-vitro anti-inflammatory activity as well potent antimicrobial activity.

Automated Methods

Radiolabeled tyrosine analogs enter cancer cells via upregulated amino acid transporter system and have been shown to be superior to18F-fluoro-2-deoxy-D-glucose (18F-FDG) in differential diagnosis in cancers. In this study, we synthesized O-[3-19F-fluoropropyl]-α-methyl tyrosine (19F-FPAMT) and used manual and automated methods to synthesize O-[3-18F-fluoropropyl]-α-methyl tyrosine (18F-FPAMT) in three steps: nucleophilic substitution, deprotection of butoxycarbonyl, and deesterification. Manual and automated synthesis methods produced18F-FPAMT with a radiochemical purity >96%. The decay-corrected yield of18F-FPAMT by manual synthesis was 34% at end-of-synthesis (88 min). The decay-corrected yield of18F-FPAMT by automated synthesis was 15% at end-of-synthesis (110 min).18F-FDG and18F-FPAMT were used forin vitroandin vivostudies to evaluate the feasibility of18F-FPAMT for imaging rat mesothelioma (IL-45).In vitrostudies comparing18F-FPAMT with18F-FDG revealed that18F-FDG had higher uptake than that of18F-FPAMT, and the uptake ratio of18F-FPAMT reached the plateau after being incubated for 60 min. Biodistribution studies revealed that the accumulation of18F-FPAMT in the heart, lungs, thyroid, spleen, and brain was significantly lower than that of18F-FDG. There was poor bone uptake in18F-FPAMT for up to 3 hrs suggesting itsin vivostability. The imaging studies showed good visualization of tumors with18F-FPAMT. Together, these results suggest that18F-FPAMT can be successfully synthesized and has great potential in mesothelioma imaging.
