Description:	Ulipristal (acetate) is a novel selective progesterone receptor modulator (SPRM) for the treatment of benign gynecological conditions such as uterine myoma.
In Vivo:	Ulipristal and CDB-4124 have significant antiprogestational activity in vivo[1]. Ulipristal acetate decreases incidences of fibroadenomas and adenocarcinomas in the mammary gland in all treated groups. Ulipristal acetate exposure [AUC(0-24h)] at the highest dose in rats is 67 times human therapeutic exposure at 10 mg/day. In mice, no tumor of any type increases at Ulipristal acetate exposures up to 313 times of therapeutic exposure. Ulipristal acetate-related findings in mice are limited to organ weight changes in the liver, pituitary, thyroid/parathyroid glands, and epididymis as well as minimal panlobular hepatocellular hypertrophy in male and female mice receiving 130 mg/kg/day[4]. Ulipristal acetate (1 mg/kg and 5 mg/kg) increases the frequency with which pathologists assessed the endometrium as being thickened compared to controls in a dose-dependent manner. There is a slight decrease in secretory differentiation with increasing dose of Ulipristal acetate, with small decreases in frequency of sub- and supra-nuclear vacuolation[5].
In Vitro:	Ulipristal acetate blocks activin A modulation of fibronectin and vascular endothelial growth factor A (VEGF-A) mRNA expression in cultured myometrial and leiomyoma cells[2]. Ulipristal acetate decreases the DNA fragmentation at the 100-ng/mL dose and continuing up to the 10,000-ng/mL dose compared to those spermatozoa in the control group[3].
Animal Administration:	The study consisted of four groups, each comprising four female cynomolgus monkeys. The groups eitherreceive ASV (control), or Ulipristal acetate at dose levels of 1, 5, or 25 mg/kg for 39 weeks. Two additional animals are allocated to the control and high dose groups for an 8-week post-dose recovery period. At randomization, there is no statistically significant difference between treatment groups in mean body weight. The vehicle or Ulipristal acetate is administered to all groups by oral gavage for 273 consecutive days at a dose volume of 2 mL/kg. Following the dosing or recovery period, animals are euthanized by intravenous administration of sodium pentobarbital followed by exsanguination of the femoral vessels.

Cat. No.	Product name	Field of application
DC82301	IC-8	IC8 is an ionizable cationic lipid. It has been used in combination with other lipids for the formation of lipid nanoparticles (LNPs). Immunization with severe acute respiratory coronavirus 2 (SARS-CoV-2) spike glycoprotein mRNA in IC8- and manganese-containing LNPs induces IgG responses to SARS-CoV-2 Delta and Omicron variants in mice.1 Administration of mRNA encoding B7-H3 X CD3 bispecific T cell engaging (BiTE) antibodies in IC8-containing LNPs reduces tumor growth in MV4-11 and A375 mouse xenograft models.
DC75721	CL2A-SN38 (Govitecan)	CL2A-SN38 is a SN38 derivative with a peptide-linker which can easily react with antibody to form an antibody-drug conjugate (ADC). CL2A-SN-38 is composed of a potent a DNA Topoisomerase I inhibitor SN-38 and a linker CL2A to make antibody drug conjugate (ADC). CL2A-SN-38 provides significant and specific antitumor effects against a range of human solid tumor types. CL2A is a noncleavable complicated PEG8- and triazole-containing PABC-peptide-mc linker. CL2A is cleavable through pH sensitivity, giving rise to bystander effect, and binds the antibody at a cysteine residue via a disulfide bond. .
DC46471	RP101988	RP101988, the major active metabolite of Ozanimod, is a selective, potent S1PR1 (sphingosine-1-phosphate receptor 1) agonist, with EC50s of 0.19 nM and 32.8 nM for S1PR1 and S1PR5, respectivlely.
DC37901	PD-173212	PD-173212 is a small molecule N-type calcium channel blocker.
DC37333	N,N-Diethyl-p-toluamide	N,N-Diethyl-p-toluamide is a mosquito repellent.
DC37321	AI3-15902	AI3-15902 is a biochemical.
DC37283	Methyl phenylcarbamate	Methyl phenylcarbamate is a biochemical.
DC37252	Ampyrone	Ampyrone is a metabolite of AMINOPYRINE with analgesic and anti-inflammatory properties. It is used as a reagent for biochemical reactions producing peroxides or phenols. Ampyrone stimulates LIVER MICROSOMES and is also used to measure extracellular water.
DC37245	Piperonyl butoxide	Piperonyl butoxide (PBO) is an organic compound used as a component of pesticide formulations. It is a waxy white solid. It is a synergist. That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone.[1] It is a semisynthetic derivative of safrole.
DC36443	DC-Chol	DC-Chol is a cationic cholesterol derivative. DC-Chol, as a component of lipoplexes with DOPE, has been used for transfection of mRNA into A549 cells without affecting cell viability. Incubation of DC-chol/DOPE liposomes or lipoplexes with human whole blood has no effect on neutrophil elastase or β-thromboglobulin levels or the number of platelets and red and white blood cells, indicating hemocompatibility. DC-Chol has also been widely used in the synthesis of liposomes for the delivery of siRNA, DNA, and chemotherapeutic agents into cells and mice.
