Monotargeting anticancer agents suffer from resistance and target nonspecificity concerns, which can be tackled with a multitargeting approach. The combined treatment with HDAC inhibitors and PPARγagonists has displayed potential antitumor effects. Based on these observations, this work involves design and synthesis of molecules that can simultaneously target PPARγand HDAC. Several out of 25 compounds inhibited HDAC4, and six compounds acted as dual-targeting agents. Compound 7i was the most potent, with activity toward PPARγEC50 = 0.245 μM and HDAC4 IC50 = 1.1 μM. Additionally, compounds 7c and 7i were cytotoxic to CCRF-CEM cells (CC50 = 2.8 and 9.6 μM, respectively), induced apoptosis, and caused DNA fragmentation. Furthermore, compound 7c modulated the expression of c-Myc, cleaved caspase-3, and caused in vivo tumor regression in CCRF-CEM tumor xenografts. Thus, this study provides a basis for the rational design of dual/multitargeting agents that could be developed further as anticancer therapeutics.

Recently, we have reported that non-hydroxamate thiazolidinedione (TZD) analogs are capable of inhibiting human deacetylase 4 (HDAC4). This study aims at the dissection of the molecular determinants and kinetics of the molecular recognition of TZD ligands by HDAC4. For this purpose, a structure activity relationship analysis of 225 analogs was combined with a comprehensive study of the enzyme and binding kinetics of a variety of HDAC4 mutant variants. The experimental data were rationalized by docking to the two major conformations of HDAC4. TZD ligands are competitive inhibitors and bind via a two-step mechanism involving principal molecular recognition and induced fit. The residence time of 24 g is (34 ± 3) min and thus much larger than that of the canonical pan-HDAC inhibitor SAHA ((5 ± 2) min). Importantly, the binding kinetics can be tuned by varying the structure of the CAP group.

Cancer cells increase their glucose uptake and glycolytic activity to meet the high energy requirements of proliferation. Glucose transporters (GLUTs), which facilitate the transport of glucose and related hexoses across the cell membrane, play a vital ro

Thiazolidinedione (TZD) has been an interesting scaffold due to its proven antidiabetic activity and encouraging findings in anticancer drug discovery. We synthesised benzylidene thiazolidinedione derivatives which exhibited excellent antiproliferative effects in chronic myeloid leukemic cells K562 and the most active compounds 3t and 3x had GI50 value of 0.9 and 0.23 μM respectively. Both the compound was found to arrest the growth of K562 cells in G0/G1 phase in a time and dose dependent manner. Further, western blot analysis revealed that 3t and 3x could also inhibit the expression of cell proliferation markers, PCNA and Cyclin D1 and compound 3x up-regulated apoptosis markers, cleaved PARP1 and activated caspase 3, which could be a possible mechanism for the excellent antiproliferative effects exhibited by these compounds. In vitro combination studies of 3t and 3x with Imatinib found to potentiate the antitumor effects of Imatinib. Further in vivo efficacy in K562 xenografts, of 3t and 3x alone and in combination with Imatinib was found to be promising and far better than control group and combination treatment was found to be more effective as compared to only Imatinib treated or test compound treated animals. Thus, our findings suggest that these compounds are promising antitumor agents and could help to enhance the anticancer effects of Imatinib and other tyrosine kinase inhibitors, when used in combination.

A series of 5-(4-substituted benzylidene-2-(substituted benzo[d]thiazol-2-ylimino)thiazolidin-4-one (5a-r) have been synthesized from 2-aminobenzothiazole as starting material. Condensation of thiazolidin-4-one with different substituted aromatic benzaldehyde occurred at reactive methylene group present at C-5 position of thiazolidin-4-one ring and resulted in the formation of compounds (5a-r). These were characterized using physical and spectral methods. The compounds (5a-r) were evaluated for analgesic and antiinflammatory activity using in vivo models.

A new series of 2-(4-methyl-2-oxo-2H-chromen-7-yloxy)-N-(benzo[d]thiazol-2- yl)acetamide derivatives (4a-k) was synthesized and evaluated for their D 2 and 5HT2 antagonistic activity as a measure of atypical antipsychotic property. Compounds (4a-k) were synthesized by refluxing various N-(benzothiazol-2-yl)-2-chloroacetamides substituted derivatives (3a-k) with 7-hydroxy-4 methyl-2H-chromen-2-one (1) in acetonitrile and anhydrous K 2CO3. N-(Benzothiazol-2-yl)-2-chloroacetamides substituted derivatives (3a-k) were prepared from the chloroacetyl chloride with various 2-amino benzothiazole substituted derivatives (2a-k). The synthesized compounds were characterized with the help of spectral and analytical data. Most of these compounds showed dopamine D2 receptor antagonistic activity from moderate to high affinity along with serotonin 5-HT2 receptor blockage activity: a property that has been suggested as necessary for atypicality. The D 2 and 5-HT2 receptor blockage activity was evaluated by inhibition of apomorphine-induced climbing behaviour and 5HTP induced head twitches in mice, respectively.
