The application relates to the application of lycorine hydrochloride in the preparation of a medicine for inhibiting the proliferation of a neointimal in a blood vessel. Lycorine hydrochloride has the effect of inhibiting the proliferation of a neointimal in a blood vessel, and the effect is mainly realized by inhibiting the proliferation and migration of vascular smooth muscle cells. In the body, the results show that lycorine hydrochloride can significantly inhibit the intimal proliferation caused by left common carotid artery ligation, and in vitro experiments prove that lycorine hydrochloride can intervene in the proliferation, migration and phenotype transformation of VSMCs induced by PDGF-BB. Lycorine hydrochloride inhibits the proliferation, migration and phenotype transformation of VSMCs induced by PDGF-BB, and the proliferation of a neointimal in a blood vessel through a MAPKs signal path. The application provides data for preparing lycorine hydrochloride into a medicine for inhibiting the proliferation of a neointimal in a blood vessel, and is expected to be applied to the prevention and treatment of complications after percutaneous coronary intervention, such as restenosis or in-stent thrombosis, and can become a potential medicine for intervening in restenosis.

To provide a heterocyclic compound and its use.SOLUTION: Provided herein are novel heterocyclic compounds, e.g., compounds having Formula I, I-P, II, II-P, III, or IV. Also provided herein are pharmaceutical compositions comprising the compounds and methods of using the same, for example, in the inhibition of aldehyde dehydrogenase, retinoid pathway activation, and / or to treat various cancers, cancer metastasis, type 2 diabetes, pulmonary arterial hypertension (PAH), or neointimal hyperplasia (NIH), or as a male contraceptive.SELECTED DRAWING: Figure 1A

The present disclosure provides pro-angiogenic proteoglycan mimetics that can provide a provisional, pro-angiogenic scaffold to support tissue regeneration while limiting systemic exposure to VEGF activity. These mimetics can protect a collagen matrix from rapid degradation, and in conjunction with EPCs promote angiogenesis in order to accelerate ischemic wound healing. For example, the provided compounds can be delivered from the end of a catheter following balloon angioplasty to coat the collagen exposed areas, prevent platelet binding and thrombosis, support capture of EPCs from blood to facilitate reendothelialization, and reduce late-lumen loss (neointimal hyperplasia).
