The total synthesis of berberine and selected analogues. And their evaluation as amyloid β (Aβ) aggregation inhibitors is described. The key step in the synthesis, the assembly of the berberine framework, was accomplished using an intermolecular Heck reaction. Berberine analog 17 incorporating a tertiary amine moiety showed good anti Aβ aggregation activity, water solubility, and almost no toxicity to nerve cells.

Transient receptor potential vanilloid type 3 (TRPV3) is a Ca2+ permeable nonselective cation channel and expressed abundantly in skin keratinocytes. TRPV3 emerges as an attractive target for treatment of pruritic, inflammatory, pain and skin-related diseases. However, only a few reports of TRPV3 inhibitors exist at present besides some patents. Therefore, TRPV3 research has always been fraught with challenges. Through a combination of virtual screening and biological evaluation, compound P1 (10 μM) was identified as a top hit with 34.5% inhibitory effect on 2-APB (1 mM)-evoked currents of mTRPV3-WT. Further structural optimization provided the inhibitor PC5 with the best activity (IC50 = 2.63 ± 0.28 μM), and point mutation assays indicated that amino acids V629 and F633 are crucial for the binding of PC5 and TRPV3. In summary, these newly discovered inhibitors could serve as promising lead compounds for the development of TRPV3 inhibitors in the future.

In recent years, focusing on new potent anticancer agents with selective activity is one of the greatest challenges in cancer therapy. Breast cancer is the most common cancer and the main cause of cancer deaths in women. The sulfatase enzyme plays an important role in converting the sulfated steroids into non-sulfate steroid hormones, which increases the growth and development of many hormone-dependent cancers, such as breast cancer. In this regard, structure-based optimization was conducted to design novel flavone-sulfonates pharmacophore as a new steroid sulfatase inhibitor. In the present work, the conventional methods for the synthesis of 4-oxo-2-phenyl-4H-chromen-7-yl methanesulfonate derivatives were reported. Their cytotoxicity was evaluated with MTT assay against a breast cancer cell line (MCF-7). The apoptosis inducing activity of the most cytotoxic compound 3c with an IC50 value of 0.615 μM was evaluated in comparison to docetaxel in the presence of estradiol which is a crucial growth factor to survive the cancerous cells. The results of double staining Annexin V-FITC/PI analysis suggested that the cytotoxic activity of this compound 3c in MCF-7 cells occurs via apoptosis. Molecular docking studies were conducted to clarify the inhibition mode of the most promising compound (3c) over the sulfatase (1P49) binding site. The analysis revealed the role of hydrogen bond interaction with Gly181 and hydrophobic interactions through the 1P49 active site in the ligand-receptor complex as significant descriptors to rationalize the potential inhibition activity.

Steroid sulfatase (STS) is a sulfatase enzyme that catalyzes the conversion of sulfated steroid precursors to free steroid. The inhibition of STS could abate estrogenic steroids that stimulate the proliferation and development of breast cancer, and therefore STS is a potential target for adjuvant endocrine therapy. In this study, a series of 3-benzylaminocoumarin-7-O-sulfamate derivatives targeting STS were designed and synthesized. Structure-relationship activities (SAR) analysis revealed that attachment of a benzylamino group at the 3-position of coumarin improved inhibitory activity. Compound 3j was found to have the highest inhibition activity against human placenta isolated STS (IC50 0.13 μM) and MCF-7 cell lines (IC50 1.35 μM). Kinetic studies found compound 3j to be an irreversible inhibitor of STS, with KI and kinact value of 86.9 nM and 158.7 min?1, respectively.

Aiming to deepen the structure–activity relationships of the two P-glycoprotein (P-gp) modulators elacridar and tariquidar, a new series of amide and ester derivatives carrying a 6,7-dimethoxy-2-phenethyl-1,2,3,4-tetrahydroisoquinoline scaffold linked to different methoxy-substituted aryl moieties were synthesised. The obtained compounds were evaluated for their P-gp interaction profile and selectivity towards the two other ABC transporters, multidrug-resistance-associated protein-1 and breast cancer resistance protein, showing to be very active and selective versus P-gp. Two amide derivatives, displaying the best P-gp activity, were tested in co-administration with the antineoplastic drug doxorubicin in different cancer cell lines, showing a significant sensitising activity towards doxorubicin. The investigation on the chemical stability of the derivatives towards spontaneous or enzymatic hydrolysis, showed that amides are stable in both models while some ester compounds were hydrolysed in human plasma. This study allowed us to identify two chemosensitizers that behave as non-transported substrates and are characterised by different selectivity profiles.
