Abstract: This disclosure relates generally to cannabinoid derivatives having the structural formula (I), pharmaceutical compositions comprising them, and methods of using the cannabinoid derivatives. In some embodiments, R1 is —CH2CH?C(CH3)2, R2 is methyl, R3 is CsHn, R4 is —C(O)N(R4a)(R4b), R5 is H, R6 is OH, and R7 is H. Compounds of the present disclosure were tested in agonist and antagonist mode for both the CB1 and CB2 receptors. The tested compounds were generally found to exhibit activity in antagonist mode at the CB1 and CB2 receptor.

Abstract: Disclosed herein is a method of using a hyaluronan conjugate, which includes a hyaluronic acid (HA), a sex hormone, and a linker for coupling one of the disaccharide units of the HA and the sex hormone. The hyaluronan conjugates are used in treating neurodegenerative diseases.

Abstract: This disclosure relates to cannabinoid derivatives of Formula (I), wherein R4 or R7 is a carboxamide group, pharmaceutical compositions comprising these compounds and methods of using the cannabinoid derivatives. These compounds are potential cannabinoid receptor inhibitors, including CB1 and CB2 receptors.

Abstract: This disclosure relates generally to cannabinoid derivatives having the formula (I), wherein R4 is hydrogen, —C(Q1)N(R4a)(R4b) or —C(R4J)(R4k)N(R4e)C(0)R4f, R6 is hydrogen, —C(Q2)N(R6a)(R6b) or —C(R6J)(R6k)N(R6e)C(0)R6f, provided that R6 is not hydrogen when R4 is hydrogen. Pharmaceutical compositions for the prevention or treatment of a disease associated with a cannabinoid receptor (such as CB1 or CB2) in a subject in need thereof, and methods of using the cannabinoid derivatives are also described.

Abstract: Disclosed herein is a method for preparing a hyaluronan-drug conjugate. The method uses the ethyl cyano(hydroxyimino)acetate/diisopropylcarbodiimide coupling system in a homogeneous reaction phase, which unexpectedly improves the substitution rate and substitution efficiency of hyaluronan-drug conjugates for various drugs.

Abstract: The present invention discloses use of butylidenephthalide (Bdph), a method of using the same, and a method for preparing a pharmaceutical composition containing the same. Because Bdph has the capability of promoting the hair growth and reducing the ?-amyloid protein (A?) level in nerve cells, the efficacy of improving the health and appearance of a subject can be achieved by administrating an effective amount of Bdph to the subject. Specifically, the Bdph has the efficacy of preventing or treating neurodegenerative diseases such as Alzheimer's disease caused by excessive build up of A? in the cells, and as an active ingredient in a topical composition, the Bdph is effective in promoting the hair growth at the site where the Bdph is administered.

Abstract: Disclosed herein are photosensitizer particle contrast agents suitable for medical imaging and/or photodynamic therapy. The photosensitizer particle contrast agent has a shell and a core encased by the shell. The shell consists essentially of multiple photosensitizer conjugates. Each photosensitizer conjugate consists of a photosensitizer and at least one biodegradable polymer covalently bound to the photosensitizer. According to certain examples, the core has an echogenic contrast-enhancing material loaded therein. In alternative examples, the photosensitizer of at least one of the multiple photosensitizer conjugates has a magnetic contrast-enhancing agent, e.g., a paramagnetic ion, chelated thereto. Also disclosed herein are methods for medical imaging which use imaging compositions containing the photosensitizer particle contrast agents taught in the present disclosure.
