Novel 2-imino-1,3-thiazoline based compounds represented by Chemical Formula I, and T-type calcium channel inhibitors containing the compound are provided. The T-type calcium channel inhibitors according to the present invention are useful as a treating agent of diseases associated with over-expression of the T-type calcium channel.

The present application relates to calcium channel inhibitors containing compounds of formula (I)

wherein Ar¹, n, R¹, X and Y are as defined in the specification. The present application also relates to compositions comprising such compounds, and methods of treating conditions and disorders using such compounds and compositions.

This invention is about a functional after-operation isolation membrane and method for making same. The functional after-operation isolation membrane is composed of the drugs taken by biodegradable isolation membrane host material, and the drugs contain antiphlogiston drugs, fibrin inhibitor drugs, calcium channel inhibitor drugs, anticoagulant drugs and antibiotics drugs or one or several kinds of Chinese patent drugs; while the isolation membrane host material is made of one or several kinds degradation rate differed materials, whose half-decay times are 1 week to 6 months. Alerting membrane materials kinds and charging amount, drugs kinds and charging amount and isolation membrane layers can make multifunctional, degradation rate different and drug-release characteristic different functional after-operation isolation membrane products, so as to adapt to different using demands. Experiments prove that this functional after-operation isolation membrane can effectively accelerate tissue healing after operation, diminish infection and prevent after-operation adhesions.

wherein Ar¹, Ar², L¹, L², n, R¹, R⁴, X and Y are as defined in the specification. The present application also relates to compositions comprising such compounds, and methods of treating conditions and disorders using such compounds and compositions.

A regime or regimen for loosening/slackening and/or relaxing cutaneous and/or subcutaneous human skin tissue, advantageously for cosmetically/therapeutically treating skin wrinkles and fine lines, comprises administering to a candidate subject in need of such treatment, a thus-effective amount of at least one inhibitor of at least one calcium channel.

The invention discloses a biodegradable shape-memory polymer based composite material used for loading drugs, which comprises 100 portions of biodegradable polymer material and 0.01 to 25 portions of drugs, wherein, the drugs refer to one of or a mixture from more than one of antibiotics, hormone, a fibrous protein inhibitor, an anticoagulant, a calcium channel blocker, an antiphlogistic drug or a Chinese patent drug. The material not only has good properties of biodegradable shape-memory polymer material, but also is loaded with effective drug ingredients, thereby being capable of providing the function with controllable time of long-term and effective treatment for patients, quickening the physical rehabilitation of patients, reducing the drug dosage of the patients with oral administration or injection and alleviating pains and inconvenience of the patients.

The invention discloses a therapeutically active compositions of matter and member species thereof which comprise indazole-containing compounds, said compounds and their therapeutic activity resulting directly from an indazole-for-catechol bioisostere replacement of a catechol-containing compound having the same therapeutic activity, where non-catechol substituents are the same or homologous before and after said replacement, and wherein said compositions of matter comprise a compound of Formula (I<1>) or (I<2>), or a pharmaceutically acceptable salt thereof, wherein in a preferred embodiment R is hydrogen; R is cyclohexyl; and R is ethyl. Ra and Rb are each individually and independently hydrogen or non-catechol substituents of said compounds resulting directly from an indazole-for-catechol bioisotere replacement of said catechol-containing compound having said therapeutic activity, where said non-catechol substituents are the same or homologous before and after said replacement, provided that both of Ra and Rb cannot be hydrogen at the same time. The therapeutic activity involved may comprise cholinesterase inhibitory activity, adrenergic alpha 1-antagonist and beta 1-agonist activity, calcium channel inhibitory activity, antineoplastic activity, and phosphodiesterase type IV inhibitor activity.

The present application relates to: (a) compounds of Formula (I):

and salts thereof, wherein Z¹, Z², Z³, Z⁴, R¹, R², and R³ are as defined in the specification; (b) compositions comprising such compounds and salts; and (c) methods of use of such compounds, salts, and compositions, particularly use as calcium channel inhibitors.

The invention discloses an application of a valeriana jatamansi Jones part in preparation of an N-type calcium channel inhibitor and belongs to the field of medicine. The effect of the valeriana jatamansi Jones part in the N-type calcium channel inhibition is provided and two iridoid components of the valeriana jatamansi Jones part for playing a role in the N-type calcium channel inhibition are verified. The inhibition effect of the acidic hydrolysis product of the iridoid in the N-type calcium channel is firstly found. The valeriana jatamansi Jones part provided by the invention taken as a novel N-type calcium channel inhibitor has a wide application prospect and can be applied to the healthcare and treatment of the related diseases such as pain.

The invention provides a manidipine hydrochloride compound. Manidipine hydrochloride is a lipophilic third generation dihydropyridine calcium channel blocker, and is mainly used for inhibiting calcium influx by inhibiting L type calcium channels on vascular smooth muscle, so as to realize relaxation of vascular smooth muscle and reduce blood pressure.

Presented herein are compounds that inhibit T-type Ca2+ channel activity in a cell when the cell membrane potential is about -90 mV. Preferred compounds inhibit T-type Ca2+ channel activity with an IC50 of 10 [mu]M or less at a membrane potential of about -90 mV. Preferred compounds show selectivity for inhibiting T-type Ca2+ channel activity at about -90 mV, relative to inhibition of T-type Ca2+ channel activity at about -30 mV to -60 mV, of 10: 1 or less. Also provided are methods for identifying compounds that inhibit T-type Ca2+ channel activity in a cell when the cell membrane potential is about -90 mV, and compounds identified by such methods.
