Chlorine-containing compound and application thereof as antifungal drug
-
Paragraph 0027-0040, (2021/05/12)
The invention discloses a chlorine-containing compound and application thereof as an antifungal drug. The invention claims to protect a compound as shown in a formula I or pharmaceutically acceptable salts, esters and solvates thereof. In the formula I, R is -NH2 or -N=C(CH3)2. Compared with itraconazole, fluconazole and amphotericin B, the compound as shown in the formula I provided by the invention has a smaller MIC value, which shows that the compound has a more excellent antifungal effect.

Acetylation, which targets a broad range of histone and non-histone proteins, is a reversible mechanism and plays a critical role in eukaryotic genes activation/deactivation. Acetyltransferases are very well conserved through evolution. This allows the use of a simple model organism, such as budding yeast, for the study of their related processes and to discover specific inhibitors. Following a simple yeast-based chemogenetic approach, we have identified a novel HAT (histone acetyltransferase) inhibitor active both in vitro and in vivo. This new synthetic compound, 1-(4-(4-chlorophenyl)thiazol-2- yl)-2-(propan-2-ylidene)hydrazine, named BF1, showed substrate selectivity for histone H3 acetylation and inhibitory activity in vitro on recombinant HAT Gcn5 and p300. Finally, we tested BF1 on human cells, HeLa as control and two aggressive cancer cell lines: a neuroblastoma from neuronal tissue and glioblastoma from brain tumour. Both global acetylation of histone H3 and specific acetylation at lysine 18 (H3AcK18) were lowered by BF1 treatment. Collectively, our results show the efficacy of this novel HAT inhibitor and propose the utilization of BF1 as a new, promising tool for future pharmacological studies.

Recently we described some (thiazol-2-yl)hydrazones as antiprotozoal, antifungal and anti-MAO agents as well as Gcn5 HAT inhibitors. Among these last compounds, CPTH2 and CPTH6 showed HAT inhibition in cells and broad anticancer properties. With the aim to identify HAT inhibitors more potent than the two prototypes, we synthesized several new (thiazol-2-yl)hydrazones including some related thiazolidines and pyrimidin-4(3H)-ones, and we tested the whole library existing in our lab against human p300 and PCAF HAT enzymes. Some compounds (1x, 1c', 1d', 1i' and 2m) were more efficient than CPTH2 and CPTH6 in inhibiting the p300 HAT enzyme. When tested in human leukemia U937 and colon carcinoma HCT116 cells (100 μM, 30 h), 1x, 1i' and 2m gave higher (U937 cells) or similar (HCT116 cells) apoptosis than CPTH6, and were more potent than CPTH6 in inducing cytodifferentiation (U937 cells).
