If you want block some range of IP's to access some network you can do that with extended access-list like below. Assuming the source network is 192.168.2.0/24 and destination network is 10.10.2.0/24 The the access-list would be like below.
int vlan10 ip address 192.168.2.1 255.255.255.0
ip access-group vlan10 in
int vlan20 ip address 10.10.2.1 255.255.255.0
ip access-list ext vlan10 deny ip 192.168.2.0 0.0.0.255 10.10.2.0 0.0.0.255
Still as mentioned by Alen, tell us what you want block and little about the topology.
