Published: January 2011

Eight new amide alkaloids (1-8) and 19 known ones were isolated from the whole plant of Piper boehmeriaefolium. Their structures were determined through spectroscopic data analyses. Cytotoxic activity of these amides against human cervical carcinoma HeLa cells was evaluated, and 1-[(9E)-10-(3,4-methylenedioxyphenyl)-9-decenoyl]pyrrolidine (9) exhibited significant inhibitory activity with an IC(50) value of 2.7 μg/mL.

Here, we describe a rare case of drug-induced unilateral ciliary body effusion precipitated by topical brinzolamide, presenting acutely with pain, angle closure and myopic shift.Ciliary body effusion was suspected clinically and confirmed by ultrasound biomicroscopy. Brinzolamide was ceased, atropine instilled and the ciliary body effusion promptly resolved without need for further treatment.

In situ forming gels as subcutaneous delivery systems of curcumin and piperine.

Sci Rep

January 2025

Department of Chemical, Pharmaceutical and Agricultural Sciences, University of Ferrara, I-44121, Ferrara, Italy.

In this study an in situ forming gel for curcumin and piperine delivery is investigated as a long-lasting strategy in the local treatment of inflammatory and degenerative joint disease, such as osteoarthritis and rheumatoid arthritis. Particularly glyceryl monooleate, in association with phosphatidylcholine and ethanol, were employed. Different ratios between excipients were tested, with the aim to obtain a liquid form suitable for subcutaneous injection, gaining a semisolid consistency in contact with biological fluids.

The current project was designed to develop piperine-loaded solid lipid microparticles (SLMs) to assess the anti-arthritic potential of piperine (PIP). Variable proportions of carnauba wax, beeswax, and tween 80 were employed for preparing SLMs by using the solvent evaporation technique. The developed formulations were subjected to particle size measurements, entrapment efficiency (EE), and zeta potential (ZP) determination.
