Adenosine pathway, including its generating enzyme (CD73) and its receptors represents a key target for cancer immunotherapy. Here we aimed to search for novel compounds able to co-target the CD73 and the A2A adenosine receptor (A2A

A series of N-alkylated saccharin derivatives were synthesized and tested for the inhibition of four different isoforms of human carbonic anhydrase (CA, EC 4. 2.1.1): the transmembrane tumor-associated CA IX and XII, and the cytosolic CA I and II. Most of the reported derivatives inhibited CA XII in the nanomolar/low micromolar range, hCA IX with KIs ranging between 11 and 390 nM, whereas they were inactive against both CA I (KIs >50 μM) and II (KIs ranging between 39.1 nM and 50 μM). Since CA I and II are off-targets of antitumor carbonic anhydrase inhibitors (CAIs), the obtained results represent an encouraging achievement for the development of new anticancer candidates without the common side effects of non-selective CAIs. Moreover, the lack of an explicit zinc binding function on these inhibitors opens the way towards the exploration of novel mechanisms of inhibition that could explain the high selectivity of these compounds for the inhibition of the transmembrane, tumor-associated isoforms over the cytosolic ones.

Facile and green syntheses of potential analgesic and antipyretic compounds, N-(4-ethoxy-phenyl)-2-(1,3- dioxo-1,3-dihydroisoindol-2-yl)acetamide derivatives 6a-g and N-[(4-ethoxy-phenylcarbamoyl)methyl]phthalamic acid derivatives 10a-g have been developed. Two synthetic routes (A and B) have been established for the preparation of 6a-g. In the route-A, 4-ethoxyaniline 2 was reacted with chloroacetyl chloride 3 in a solution of potassium acetate and acetic acid to yield N-(4-ethoxyphenyl)-2-chloroacetamide 4. The latter was reacted with imide compounds 5a-g either in triethanolamine as a green solvent or in solid phase in the presence of TEBAC and KI to yield 6a-g. Alternatively, in the route-B, reaction of anhydrides 7a-g with glycine 8 yielded the (1, 3-dioxo-1, 3-dihydroisoindol-2-yl)acetic acid derivatives 9a-g which on reaction with 2 either in triethnolamine and DCC as a dehydrating agent or in solid phase in the presence of DCC gave 6a-g. The latter were hydrolyzed in 0.5N ethanolic KOH to afford 10a-g.

Synthesis and properties of N-substituted saccharin derivatives

, p. 384 - 392 (2007/10/03)
Four different routes for the synthesis of saccharin containing peptids were studied. While reactions between saccharin sodium and α-halogeno acids were limited to two examples, reactions of sulfobenzoic anhydride (4) or saccharin-N-carboxylate (6) with amino acid esters yielded the ring opened products 5 and 7. Finally, we found, that the reaction between the benzoxathiol derivative 8 and amino acid derivatives represents a versatile route to the peptidic compounds 9 and 11. Hydrolysis and hydrogenolysis were studied, and by combination of the different routes the "saccharin tripeptides" 18 were obtained. Structures and stereochemistry were elucidated by spectroscopic and chromatographic methods. Selected compounds were tested as sweeteners of as inhibitors of elastase, but no exiting results were found.
Acid derivatives of benzisothiazole-1,1-dioxide as inhibitors of rat lens aldose reductase

A number of 6-substituted 1,2-benzisothiazole-1,1-dioxide alkanoic acids were synthesized and evaluated for crude rat lens aldose reductase inhibitory activity. The inhibitory potency of the acetic (6a, 10a), propionic (6b, 10b, 11b), and isopropionic (6c, 16c, 11c) derivatives was very similar and generally lower than that of the reference compound, Sorbinil. The presence of an acyl moiety on the amino group in position 6, as in the acetic and propionic derivatives 14a-f and 15a,b, respectively, resulted in a significant increase in activity. A good potency was shown by compounds 14g and 15g, in which a second carboxylic function is present on the 6-acylamino group. Also the open products 16, which contain the phenylsulfonyl fragment found in several known inhibitors of aldose reductase, were obtained and tested in the rat lens assay.
